Defensive Glossary
### Clean Sheet
A clean sheet is recorded when a team prevents the opposition from scoring any goals during an entire match. For Arsenal in 2025, this statistic is a primary measure of defensive solidity. It reflects not just the work of the goalkeeper and defenders, but the entire team's commitment to a structured defensive shape. The frequency of clean sheets is often correlated with a team’s ability to challenge for the Premier League title, as it guarantees at least one point and provides a platform for the attack to win the game.### Goals Conceded
This is the total number of goals an opponent scores against Arsenal in a given competition or period. In the 2024-25 season, this figure is tracked across the Premier League, UEFA Champions League, and domestic cup competitions. A lower goals-conceded tally is the most direct indicator of defensive effectiveness. Analysts often look at this number in conjunction with expected goals against (xGA) to determine if the defensive performance is sustainable or if it is being propped up by exceptional individual performances.### Expected Goals Against (xGA)
A more advanced metric, Expected Goals Against (xGA), measures the quality of chances an opponent creates against Arsenal. Each shot is assigned a probability of scoring based on factors like distance, angle, and type of assist. Summing these probabilities provides an xGA total. If Arsenal’s actual goals conceded is lower than their xGA, it may suggest excellent goalkeeping or a degree of luck. Conversely, a higher goals conceded than xGA indicates defensive frailties that might not be obvious from the scoreline alone.### Saves
This statistic counts the number of times the Arsenal goalkeeper successfully prevents an opponent’s shot from entering the goal. In 2025, the saves-to-shots ratio, or save percentage, is a key performance indicator for the number one. A high number of saves can indicate either a busy goalkeeper or a porous defence, while a lower number of saves with a high percentage often points to a well-organised backline that limits high-quality chances.### Save Percentage
Calculated as total saves divided by total shots on target faced, this percentage provides a more nuanced view of goalkeeping performance than raw saves alone. A save percentage above 70% is generally considered strong. For Arsenal, maintaining a high save percentage is crucial, as it ensures that the few chances conceded are not routinely converted into goals.### Shots on Target Against
This is the number of opponent shots that are directed towards the Arsenal goal and would have gone in if not saved or blocked by a defender. It is a measure of how often the opposition is able to test the goalkeeper. A low number of shots on target against is a positive sign, indicating that the defensive system is effectively forcing opponents into low-quality or blocked attempts.### Shots Faced
A broader metric than shots on target, this counts every shot attempt made by the opponent, including those that are blocked or go wide. In Arsenal’s case, a high number of shots faced can be a warning sign, even if many are from distance. It suggests that the team is allowing the opposition too much time and space in dangerous areas, even if the final product is lacking.### Tackles
A tackle is a defensive action where a player dispossesses an opponent of the ball. For Arsenal defenders and midfielders, the number of tackles is a measure of their engagement and aggression. However, a high tackle count can also indicate that a player is frequently out of position and having to recover, rather than intercepting the ball proactively. The success rate of tackles is often a more telling statistic than the total number.### Interceptions
An interception occurs when a player reads the opponent’s pass and cuts it out before it reaches its intended target. This is a highly valued skill in Mikel Arteta’s system, as it allows Arsenal to win the ball high up the pitch and transition quickly into attack. A high interception rate from the centre-backs and defensive midfielders is a hallmark of a well-drilled defensive unit.### Clearances
This is a defensive action where a player kicks or heads the ball away from the goal area, often under pressure. While a necessary part of defending, a very high number of clearances can indicate that a team is camped in its own half and struggling to play out from the back. For Arsenal, the goal is to keep this number relatively low by building possession and relieving pressure through controlled passing.### Blocks
A block is recorded when a defensive player uses their body to stop a shot from reaching the goal. This can be a crucial last-ditch effort, especially from defenders who sacrifice their body to protect the net. The number of blocks by Arsenal’s defenders is a testament to their bravery and commitment to the team’s defensive cause.### Aerial Duels Won
This statistic tracks the percentage of contested headers that an Arsenal player wins. In the Premier League, dominance in aerial duels is vital for defending set pieces and long balls. A strong aerial duel win rate from the centre-backs, such as William Saliba and Gabriel Magalhães, provides a solid foundation for dealing with direct opposition tactics.### Dribbled Past
This is the number of times an opponent successfully dribbles past an Arsenal defender. A low dribbled-past count is a sign of good one-on-one defending. For full-backs in particular, who are often isolated in wide areas, minimising this statistic is a key objective. A high number can expose the team to dangerous crosses and cut-backs.### Fouls Committed
The total number of fouls made by Arsenal players in defensive situations. While a tactical foul can break up a dangerous counter-attack, a high number of fouls in dangerous areas around the penalty box can lead to goals from set pieces. The discipline to avoid unnecessary fouls is a sign of a mature defensive unit.### Yellow and Red Cards
Disciplinary statistics are a crucial part of the defensive picture. Yellow cards for tactical fouls or dissent can lead to suspensions, disrupting the defensive partnership. Red cards have a more immediate and severe impact, often forcing a team to defend with ten men for a significant portion of a match. Arsenal’s ability to maintain a clean disciplinary record is essential for squad stability.### Pass Completion Percentage (Defenders)
For Arsenal, the build-up play starts from the back. The pass completion percentage of the centre-backs and goalkeeper is a vital metric. A high percentage indicates composure on the ball and the ability to play through the opposition’s press. This is not just about safety; it is about initiating attacks and controlling the tempo of the game from deep positions.### Progressive Passes (Defenders)
This more advanced metric counts passes made by defenders that move the ball significantly towards the opponent’s goal. For Arsenal’s centre-backs, this often involves line-breaking passes into the midfield or switching play to the full-backs. A high number of progressive passes from the backline is a sign of a team that is not just defending but actively building attacks.### Possession Won in Defensive Third
This statistic tracks how often Arsenal regain possession in their own defensive third of the pitch. While it is a measure of defensive work, a high number can also indicate that the team is under sustained pressure. The goal is to win the ball higher up the pitch, in the middle or attacking third, to create more immediate goal-scoring opportunities.### Pressures (Defensive Third)
Pressures are actions where a defender closes down an opponent in possession. In the defensive third, this is about preventing the opposition from having time to pick out a pass or take a shot. For Arsenal, the intensity of pressure applied by the forwards and midfielders often dictates how much work the defenders have to do in their own third.### Goals Conceded from Set Pieces
This is a specific breakdown of goals conceded from corners, free kicks, and throw-ins. In 2025, this has been a particular area of focus for Arsenal’s coaching staff. A low number of set-piece goals conceded is a sign of good organisation and aerial dominance, while a high number can be a major weakness that opponents will look to exploit.### Goals Conceded from Open Play
This metric covers all goals conceded that do not come from set pieces. It is a broader measure of how the team defends in fluid, dynamic situations. Analysing open-play goals conceded often reveals issues with defensive transitions, individual errors, or tactical mismatches against specific opponents.### Big Chances Missed (by Opponents)
While not strictly an Arsenal defensive stat, tracking the number of clear-cut opportunities the opposition squanders is informative. A high number of big chances missed by opponents can suggest that Arsenal’s defence is fortunate, or that their pressure is forcing hurried finishes. It provides context for the goals-conceded tally.### Defensive Actions Per 90 Minutes
This is a composite metric that sums tackles, interceptions, clearances, and blocks per 90 minutes of play. It provides a holistic view of a defender’s or a team’s activity level. For Arsenal, a high defensive actions per 90 can indicate a busy game, while a low number often means the team has controlled possession and limited the opponent’s opportunities.What to Check
When reviewing Arsenal’s defensive statistics for the 2024-25 season, it is important to consider the context of each match. The quality of the opposition, the match location (home or away), and the tactical approach (e.g., defending a lead vs. chasing a game) all influence the raw numbers. For the most accurate and up-to-date figures, it is recommended to consult official Premier League and UEFA statistics platforms, as well as trusted football analytics websites. These sources provide verified data that allows for a more objective assessment of the team’s defensive performance.
