Arsène Wenger says his team were “too nervous” in the opening stages of their 1-0 defeat at Manchester United on Sunday.
Robin van Persie's 28th-minute header was the difference between the two sides in a tight game with few clear-cut chances.
And the Arsenal manager was disappointed to not come away with at least a point after his side dominated possession in the second half.

"Maybe because we haven't won for a while here, we were just not ourselves in the first half. In the second half we should have come back - we were honestly unlucky," he said.Copyright 2016 The Arsenal Football Club plc.
