Arsène Wenger was questioned on his decision to play David Ospina over Petr Čech in the Champions League last night before telling the media his first choice goalkeeper was injured.

Čech was on the bench but Wenger explained that a slight calf issue had been a concern before the game at Leicester at the weekend and with Manchester United to play on Sunday the goalkeeper wasn’t risked.

However, the Daily Mail are now claiming that Čech had declared himself fit to play. The goalkeeper still started – and came through 90 minutes – at the weekend despite his original complaints but it’s understandable that he sat out the loss to Olympiacos if he was struggling.

But if he was struggling, why was he on the bench?

None of this would be a talking point had David Ospina not dropped a corner over his own line, giving Olympiacos the lead shortly before half-time. Arsenal levelled the score again only to concede the winner.

The Colombian goalkeeper has never been a particularly assuring presence in the Arsenal goal, and this latest performance may just Wenger wondering whether or not he can choose him again.

While Ospina was at fault for the goal in a spectacular way, the rest of the team didn’t perform either. Arsenal were slow moving the ball and didn’t have much energy off it. Defensively we were lax, not putting enough pressure on the ball and not staying compact enough.

Arsenal were awful all over the pitch but Ospina made a horrific error that you wouldn’t have expected of Čech.
