Arsenal manager Arsene Wenger is worried about the quality of the San Siro playing surface for Wednesday's Champions League last 16 first leg against AC Milan.
Wenger noted the pitch has been recently relaid in the wide areas and has yet to bed in properly.
"I am a bit worried about the quality of the pitch," said Wenger. "It doesn't look exceptional. Hopefully tomorrow it will be better.
"It has been relaid down the flanks very recently and you know what it is like when you have just laid a pitch like that.
"It takes time to settle and become flat. At the moment, it isn't."
Wenger also promised an attacking approach from his side.
"If I would think we have no chance to win the game I would stay at home. I don't like to waste my time," he said.
"I believe what makes football interesting is that you can win everywhere.
"We have shown we can win everywhere and I have full confidence in this team that we can do it.
"We will try to play our game. Milan are a good side. We think we are a good side.
"We will attack, they certainly will as well. So it should be a good game."
