Arsenal boss Mikel Arteta was delighted after victory at Leicester City.
Gabriel Martinelli struck immediately after halftime for the 1-0 win.
Arteta said: "I think performances. I think to do what to do what the team has done here today is very, very difficult. I think we dominated the game from the start almost to finish, we had a difficult 10 or so minutes where we gave so many balls away that we lost a little bit of control, but in general, I think our play and understanding of the space, how they were pressing, how we got into final third positions was excellent.
"We lacked a little bit of that final pass to score more or create bigger chances, I think we weren't over the decision with the disallowed goal, which was difficult to take, but to stay really focussed and determined to do that, I think defensively we were incredible because we restrict Leicester to one shot on target in the whole game at home is a difficult thing to do. The players did really well.
"Set players, sloppy goals, and individual errors, it's part of football sometimes you are going to concede in games but the fact we are not conceding and giving chances away is really important if you want to be constantly winning matches"
