Arsenal suffered a 2-0 defeat in the Capital One Cup to Chelsea last night and Thomas Vermaelen revealed his frustration as both strikes could have been avoided.
Goals from Cesar Azpilicueta and Juan Mata in either half settled the fourth round tie which sees Chelsea march on, but Vermaelen was not happy with the nature of the goals.
He told Arsenal's website: "The first goal is always important, you always want to take the lead in such a big game. It's quite disappointing they got a 1-0 lead, it was a goal we could avoid - I think both goals."
Vermaelen has only made one Premier League appearance for Arsenal so far this season, and was upset to be out of the running for a domestic trophy so early.
"It is a bit disappointing of course, I don't think they had a lot of chances to be honest, especially in the second half when we dominated the game. We couldn't create a lot of chances ourselves but at the end it's quite a disappointing result.
"I think we started well in the second half, pushing higher up, and we had the most possession of the ball. That's why the second goal killed it a little bit."
Despite being the club-captain, the Belgian hasn't been able to reinstate himself in the team's central defence since the partnership of Per Mertersacker and Laurent Koscielny formed towards the end of last season.
But although he has been linked with moves away from the club in order to secure a World Cup starting place with Belgium, the 27-year-old has called on his team-mates to focus on the Premier League game with Liverpool this weekend.
"It's really important for the league, we need to respond quickly. It's good the game is on Saturday and we can respond on the defeat from Tuesday night."
