Wenger: 'It is, of course, a major missed opportunity'

"We were in control, but as long as you do not score the third goal, you know the game is not won. In fairness, West Ham continued to fight until the last minute and we conceded from two set pieces, which were generous ones.

"I do not think that either should have been given, but we cannot influence the decision of the referee. The crowd got behind the referee's decision and then it is always difficult away from home.

"We are an intelligent team and an intelligent team makes the maximum result with the game they produce. That is what we did not do. We complicated our game a little bit and had five or six chances in the second half, but we missed the final ball. That is what we have to learn."

"It is very frustrating. It is, of course, a major missed opportunity. In our job, you don't have this luxury. You need to get points when you deserve to get points and sometimes when you don't deserve to get the points.

"Today we never got them when we deserved them - and that means we have not made the maximum of what we should have done, but we have to keep the positives as we played well and are a strong team.

"We want to learn to finish these games off which is basically the most important lesson of the day. We have a great chance for the title this year, but you cannot repeat this kind of performance we had today and not come out with three points."
