Aaron Ramsey
A loyal servant and normally a reliable big-game player, Aaron Ramsey has gone badly downhill this season and is unlikely to ever become the player we all thought he could be.
The Welshman can no longer be classed as one for the future, and in fact after a long and gruelling career at the top level with a series of injury problems, he may now be burning out.
Ramsey was invisible against Manchester City and was one of the players Gary Neville accused in commentary of ‘walking’. It may be time to give up on him as the future of this club.
Calum Chambers
While not as obviously bad as Mustafi on the day, there’s no way Calum Chambers should have been involved in a game of this magnitude.
The former Southampton youngster has done precious little in the last couple of seasons to warrant any playing time, and he seemed overawed by the occasion at Wembley.
Quite why he’s still at Arsenal is a mystery, and it surely won’t be for much longer now.
David Ospina
Finally, Arsenal need an upgrade on both their goalkeepers, with David Ospina surely the man who should make way at the Emirates.
The Colombian has never looked good enough to be first choice for the Gunners, so should make way for a top class number one as Petr Cech becomes an experienced backup and dressing room leader, perhaps moving into coaching later.
Ospina, however, just isn’t good enough for this level and his continued trust from Wenger in big games like this remains baffling to everyone who’s seen him play down the years.
