Mikel Arteta expressed satisfaction with Arsenal's summer transfer window, crediting sporting director Andrea Berta, but conceded it wasn't "perfect." The Gunners, aiming to build on their Premier League success, secured Christos Tzolis from Club Brugge for £34 million and Bruno Guimaraes from Newcastle United for £75 million as a top midfield target. Ezri Konsa joined from Aston Villa for £51 million due to injuries to William Saliba and Jurrien Saliba, while Piero Hincapie's loan became permanent and Ilan Meslier arrived as a backup goalkeeper. However, Arsenal failed to sign a world-class forward, with Vinicius Jr rejecting them for a new Real Madrid contract and Julian Alvarez holding out for Barcelona despite Arsenal's pursuit from Atletico Madrid. The club also saw significant departures, including Gabriel Martinelli to Al-Hilal for £60 million, Gabriel Jesus to Barcelona, and Leandro Trossard to Besiktas, leaving Arteta to question the strength of their attack.
