He said after the game:
"The Wolves centre-backs had an outstanding day and if we wanted an intense physical preparation for Tuesday then it was a good one. We really had to put the effort in.
"I smelled that it would be a difficult game although I was a bit surprised by their commitment and organisation. But we had a good second half. We were always on top. We played very well and we needed to play at a higher tempo. It looked as if we could score every minute."
He also spoke about Thierry Henry, who is currently going through a 'barren spell' (by his standards) with no goals in six:
"I'm not worried about him," said Wenger. "He has not scored for a while but here he created four chances in 10 minutes. He is a player you want to have on the pitch even if he doesn't score for 20 games.
"We have rested him before and it didn't come off well. He is better when he's playing every game."
