Arsenal have suffered another blow to their title chances after goalkeeper Petr Cech was ruled out for the north London derby against Tottenham Hotspur this weekend.
Cech suffered a calf injury while running back to his to his own goal after attacking a late corner with the Gunners down 2-1 against Swansea on Wednesday.
He joined up with the outfield players in Arsenal’s last ditch attempt to salvage a point from the game and he pulled up up in discomfort when he tried to return to his own half after the corner-kick and has now been ruled out of the weekend clash against Spurs.
Arsenal manager Arsene Wenger admitted Cech had been struggling with the muscle issue and it means David Ospina is likely to come in for his first league start of the season.
The development comes as defender Laurent Koscielny missed the defeat with a slight calf injury and is also a doubt for the crunch meeting with rivals Spurs at White Hart Lane.
Wenger said of Cech: “He had a little groin problem and I think he struggled a bit tonight. He will not play on Saturday. I trust completely Ospina, I have no problem with that.
“I don’t know how bad it is. It’s a muscle problem, I don’t know how long he will be out.”
The injury news compounded a bad night for Arsenal as they failed to capitalize on title rivals Leicester, Tottenham and Manchester City all dropped points.
Despite taking the lead through Joel Campbell after 15 minutes, Arsenal were caught cold by Swansea, who scored through Wayne Routledge and Ashley Williams to ease their relegation worries.
It left Arsenal, who have lost their last three games in all competitions, six points behind leaders Leicester and three behind Spurs ahead of Saturday’s encounter.
