Two red cards helped Chelsea to a 2-0 win over Arsène Wenger’s Arsenal side at Stamford Bridge on Saturday afternoon.

A second defeat in three days for the Gunners won’t go down well and, yet again, we had to play with fewer than 11 men for over half the match.

“We dug in of course, we produced a performance and the commitment we wanted,” Wenger told to BBC Sport after the game.

As well as the controversial refereeing performance from Mike Dean, the manager was quick to bemoan the way Chelsea came by their first goal. A free-kick was floated into the far post where an unmarked Kurt Zouma headed home to give the Blues the lead.

Set-pieces have been an Achilles’ heel for Arsenal in some season but to concede from one when down to 10 men is poor form indeed, as they are one element of the game hardly effected by the loss of a player.

“The regret I have is we conceded a goal from a set-piece when down to 10 men and it’s very difficult to accept,” Wenger said. “It’s now twice in three days that we’ve conceded goals from set-pieces and in a game like that you know you can’t afford that.”

Dinamo Zagreb’s second goal in Arsenal’s 2-0 loss on Wednesday came from a corner. It put the hosts 2-0 and took the game beyond us.

Similarly, as soon as we trailed with 10 men at Chelsea it was always going to be tough to get back into the match. To concede from a set-piece again was incredibly damaging, and the manager will surely be working on that on the training pitch in the coming days.
