Chelsea and Arsenal suffered defeats in the Champions League

The Gunners, now without a win from their opening two games, face Bayern Munich in a double header to get their campaign back on track.

Chelsea's defeat to Jose Mourinho's former club Porto was their FOURTH of the season - and we're still in September.

Arsenal's performance has come under fire after Arsene Wenger selected David Ospina in goal instead of Petr Cech.

Ospina was at fault for Olympiakos' second goal as he flapped at a corner and ended up catching it and stepping back over the line.

That was at 1-1 and put Wenger's men under pressure at half time.

And while Alexis Sanchez managed to turn it on again, scoring a superb header on the back of the hat-trick at the weekend, the rest of Wenger's side were clueless and naive as the Greek's grabbed a surprise victory in north London.

Wenger defended the team selection post match, but questions have been raised over his decision to leave out Cech - his £10m summer signing - in such an important game.

"A goalkeeper can make a mistake that doesn't explain that we lose the game. It happened to Petr Cech already this season [against West Ham]," he said.

"It is still possible of course to qualify but it is difficult to swallow losing a game like that. We lost it on a lack of defensive concentration and bad luck. They had four shots on goal and we conceded three goals.

"The turning point at 2-2 is we give them a goal again straight away. If it stays 2-2 for five minutes we win the game."

Arsene Wenger's big gamble did not pay off

In Portugal Mourinho’s prematch blast at his players seemed to have little effect.

Branislav Ivanovic was poor again and run ragged.

Willian had equalised Andre Andre’s opener but Maicon headed in a winner to stun the Blues.

"When you win matches, you perform well, it is easy to know your best team," Mourinho said. 

"When the team is not winning on a regular basis it is normal that you have to make changes. After games like tonight it is difficult to analyse."

But, having already fallen to more defeats this season than they did last year, something is up.

Chelsea face the dynamic Southampton on Saturday and need to turn their season around quickly.
