Nacho Monreal concedes that Arsenal still have room for improvement despite picking up their first win of the Premier League season this weekend against West Ham United.

Nacho Monreal has claimed that Arsenal still have room for improvement despite picking up their first win of the Premier League season this weekend.

The Gunners ran out 3-1 winners over West Ham United at the Emirates Stadium on Saturday, with Unai Emery getting off the mark with his new club following defeats in their opening two games.

Despite falling behind to a Marko Arnautovic strike, Arsenal hit back through Monreal and Danny Welbeck, with Issa Diop also scoring an own goal to help the hosts to all three points.

"We are really happy for getting our first three points in the competition, but obviously it hasn't been our best performance and we have to improve," Monreal told football.london. "In the first half we conceded, but we could have conceded a few more so we need to learn about that.

"But as I said before, we are really happy about getting three points and it was our target before the kickoff. Obviously we have started a new era with a new manager so we have to keep improving.

"For example, against Chelsea we did an excellent job but we conceded three goals and got zero points, and today we have to admit that we probably played worse than the other day, but we won the game so we have to keep improving. I think we are in the right way and we are learning every day in training. I think we're going to keep improving."

Arsenal return to Premier League action next Sunday with a trip to newly-promoted Cardiff City.
