Unai Emery has dedicated Arsenal's first Premier League win under his stewardship to the club's supporters as the Gunners ran out 3-1 winners over West Ham United.
The Hammers drew first blood at the Emirates Stadium when Marko Arnautovic scored on 25 minutes, but the hosts rallied round to equalise through Nacho Monreal on the half-hour mark.
Issa Diop's own goal and Danny Welbeck's late strike then turned the game round in Arsenal's favour and condemned West Ham to their third straight defeat.
"The three points were very important," Emery told Sky Sports News at full time. "Today I saw good things, but also things to improve.
"It was very important for our supporters. After 1-0, the team was improving, the players, the substitute players made the difference. It was for that I am happy but there are things we must improve. More transition. For the second half we were speaking in the dressing room and to help more inside with two midfielders. We need the balance, in the first half we suffered more than we want.
"It is clear for us we need to improve. Also, the win gives the confidence for the players. The first half, we needed calm. The players, they show every supporter we want and can do the second half going forward with balance, and win the match. We need this control with possession with the ball and also going forward with balance, which is important."
Arsenal return to Premier League action next Sunday with a trip to newly-promoted Cardiff City.
