Ander Herrera is full of praise for Manchester United teammate Michael Carrick.
Herrera admits the Geordie's leadership is valued.
"He always gives us calmness; he's a very calm guy when he's playing. He gives me confidence," says Herrera.
"He is very good for the young players because he always tries to help, not necessarily with words but with his attitude and his calmness.
"He is one of the best players I've ever played with and a very good professional," adds the Spaniard. "We can all improve by looking at him and what he does. I feel lucky to play with him."
