AC Milan midfielder Michael Essien says Manchester United are missing the leadership of Nemanja Vidic, now of Inter Milan.
The former Chelsea midfielder faces Vidic in the Milan derby on Sunday, in an echo of their tussles in the Premier League.
Essien said: "I think he (Vidic) is being missed by United because things are not really going well for them, especially when it comes to their defence.
"He is a top guy and really good defender. He gives everything and puts his body down for every tackle. It will be good to face him in another league. I will be looking forward to it and hopefully we will win."
