Wenger excited about Arsenal potential after victory over Southampton
"In the first 45 minutes we were at a particularly high level," the Gunners boss said.
"We had a good combination of pace, speed of our passing and quick combinations. The movement was excellent.
"We were quite lucky as well because they conceded two own goals, but overall I think it was a level of continuity with what we have shown at Liverpool.
"The game was very interesting to watch. We lost a bit of urgency in the second half, but that is human. We controlled the game and remained serious.
"It is a big week coming up because we go on Tuesday to Montpellier, then on Sunday we play at Man City.
"We know much more about the team. There is a positive energy in this team - a desire to play, a desire to play well together and real team play so it is very exciting."
