Manchester United striker Javier Hernandez hailed two-goal Juan Mata in victory at Newcastle United.
Chicharito also struck in the 4-0 win.
"It's unbelievable. You can see that's going to be a very important player for this club. He needed to get used to the way that we play and the way the manager wants us to play.
"In the past games, he did alright but the goal he scored against Aston Villa gave him a lot of confidence and you can see what he is capable of, with assists, with free-kicks and to score goals so he's a very important, clever player."
