Wenger made a big mistake, says Wright

Former Arsenal striker Ian Wright has hit out at Arsene Wenger in the wake of the club's 3-2 Champions League defeat against Olympiacos at the Emirates Stadium on Tuesday.

Wenger opted to start David Ospina over regular first-choice goalkeeper Petr Cech against the Greek outfit, but the decision backfired as the Gunners fell to their second loss of this season's European campaign.

Ospina was at fault for Olympiacos's second goal of the evening, as he dropped the ball over his own line, but club legend Wright has laid the blame for the defeat at Wenger's feet.

"I was worried about Ospina at the start because I believe the two centre-backs aren't confident enough as it is," Wright told BT Sport.

"There's not enough aerial supremacy in there and the goalkeeper seemed to me like he was trying to second-guess something. For somebody who's not playing often - and this is a must-win game - how can you put Ospina in goal?

"You've got to question the manager there. I think that's a big mistake.

"Why not start with Petr Cech simply because of the experience he's got? Because we had to win this game, Arsenal had to win this game.

"Normally we're out by the quarter-final, last 16, this time we've got a massive hill to climb to go that far."

Arsenal sit bottom of Group F following Tuesday's results with no points from two games, and now face a double-header against Bayern Munich, who have taken six points from their two fixtures thus far.
