AC Milan fullback Massimo Oddo admits Ronaldo's injury problems have hurt the team this season.

Ronaldo has been ruled out of the Club World Championships and Oddo said: "His absence certainly is heavy, because we know the value of Ronaldo, an important player, although he cannot express his potential because, of course, he has played very little.

"We have excellent alternatives, however, and I think that there will be no problems for the Urawa game."
