Arsenal manager Mikel Arteta held a press conference Monday to preview the UEFA Champions League semi-final second leg against Atletico Madrid [1].

The match serves as the deciding encounter for a place in the tournament final. With the teams tied after a 1-1 draw in the first leg [2], the result of Tuesday's game will determine which club advances.

Arteta said at the Emirates Stadium in London [3]. He was joined by Atletico Madrid manager Diego Simeone and Arsenal player Viktor Gyokeres [1]. The session focused on tactical preparations and the psychological momentum required to overcome the Spanish side.

Team selection remains a primary concern for the North London club. Reports indicate that four players missed training sessions leading up to the second leg [4]. This absence creates uncertainty regarding the starting lineup for the critical match.

Arteta and Simeone said to the media to outline their strategies for the encounter. The focus remains on the narrow margin of error following the stalemate in the opening match [2].

The second-leg match is scheduled for Tuesday evening, May 5, 2026 [2]. Both managers said the importance of discipline and execution in a high-stakes environment where a single goal could change the trajectory of the season.

The teams tied after a 1-1 draw in the first leg.

The 1-1 deadlock from the first leg shifts the entire pressure of the semi-final to the second leg, effectively resetting the tie. Arsenal's ability to field a full-strength squad is now the pivotal variable, as the absence of four players during training suggests potential injuries or fitness issues that could compromise Arteta's tactical plan against a defensively disciplined Atletico Madrid side.
