Arsenal boss Arsene Wenger has urged Sir Alex Ferguson to do what he can to keep Cristiano Ronaldo at Manchester United.

Wenger said: "Once you say he stays, he stays - if not, you look weak."

The Gunners were in a similar situation when Nicolas Anelka went to Real nine years ago.

Wenger, speaking at a Euro 2008 Fanzone event sponsored by Castrol, added: "The fact is you are in a weak situation as a club.

"You can think that if he sulks you could play him in the reserves, but that just doesn't work. However, it is right to take a stand against Real."
