Arsenal boss Arsene Wenger is concerned over AS Monaco's waterlogged pitch for tonight's Champions League clash.

Heavy rain has affected the playing surface in the Stade Louis II and Wenger voiced concerns that if there are more showers then it could become waterlogged.

Wenger said: "It is a little bit of a worry. There were two concerns when I was the manager. The quality of the pitch was not fantastic. I have just been up there - it is good, very good.

"The second thing is when it rains in the south of France, it rains. It doesn't drizzle. They had to postpone a game against Montpellier recently because of the rain. I hope the conditions will not be bad on the raining front."
