Herrera was superb in the 3-1 victory and pulled the strings in midfield with an intelligent range of passing.
The Spaniard grabbed the game’s opening goal just before half time before sealing the three points with a strike in the dying moments of the match.
Mata was full of praise for Herrera after what was a perfect afternoon for United.
Speaking about Herrera, Mata said: ”I think this is the first time he scores twice in a game and I’m very happy for him! The truth is he deserves it.
“He is a genius on and off the pitch and I know how happy he was after the game.”
Mata and Herrera are developing a real bond at United which has delighted fans of the club.
Along with David de Gea, United’s Spanish contingent have been making waves on the pitch as well. De Gea is enjoying his finest season in a United shirt, while Herrera and Mata are going through their best patches of form at the club. The trio’s performances have contributed to a fresh wave of confidence and optimism at Old Trafford as the team heads into Sunday’s clash against Manchester City.
