Chelsea striker Salomon Kalou believes Nemanja Vidic could be Manchester United's weak link ahead of Wednesday's Champions League final.

"We still believe that there is some weakness in their defence and that we can exploit that and score some goals," said the Ivory Coast international.

"They are like everyone, Ferdinand is a great defender, Vidic also.

"But Vidic has not played a lot because he has been injured, so that could be a weak point for them and it is up to us to play well and score a goal."
