The Daily Express says he told French journalist Pierre Menes: "Cavani? I think he is a very good player.
"In my view, he would be a very good signing, but he has also recently signed for a big team.
"It will be expensive. But there is also Falcao, he may be an option for a pure number nine, to score goals.
"I think that with Van Persie and Rooney, David Moyes needs more than just a big scorer in his team."
