"Carlos is always in a good mood and never gets mad. If he is on the bench, he just encourages his team-mates.
"Carlos is also a great singer. The name of his band is Piola Vago. When we were at Copa America, we shared the same room and the music was louder than at a disco."
Messi also thinks that the partnership between Rooney and Tevez can only get better.
"Carlos is making a big difference for Manchester United this season.
"His partnership with Rooney is already something special and I think it will only get better.
"Although they play and move similarly to one another on the pitch, they are going to help Manchester United a lot. They will scare defenders everywhere.
"Those who play the game well understand each other immediately. Good players always manage to play well together."
