The midfielder was reacting to victory at Sunderland.
He told Arsenal Player: "There was a mentality at the end of last season when we had to win games and get that fourth spot and we have carried that on into this season, especially away from home. We seem to play really well away from home and we can take that form into the home games.
"We all get on really well here - we have got a great set of lads. We have been together for four or five years, most of us. We are starting to build a real friendship and that is starting to show on the pitch."
