Juan Mata has hailed new Manchester United signing Ander Herrera as a "complete midfielder".

The 24-year-old joined the Red Devils from Athletic Bilbao last month and has impressed for the club on their pre-season tour of America.

"He is a very, very good midfielder," The Mirror quotes Mata as saying. "He's a good guy, my friend, and we've known each other since we were 15. He's top quality, he can play quick, slow and dictate the rhythm of a game.

"He can score as well. He's a very complete midfielder and can bring these qualities to the team."

Herrera set up three of the goals in Man Utd's recent 7-0 win against LA Galaxy.
