Juan Mata has paid tribute to the "top quality" of new team-mate Ander Herrera and believes the Manchester United midfielder is capable of lighting up the Premier League.
Herrera, a £28 million signing from Athletic Bilbao this summer, starred in United's 7-0 rout of LA Galaxy to begin pre-season and impressed again as Louis van Gaal's men overcame Roma 3-2 in Denver on Saturday.
And Mata is confident his countryman has all the attirbutes to make a big impact in English football.
“He is a very, very good midfielder,” Mata told reporters after the Roma win.
“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.
“I enjoy playing with quality players like him and Wayne Rooney. We try to play the same way.”
