Juan Mata was full of praise for Mason Greenwood after Manchester United's 4-0 win over AZ Alkmaar.

The 18-year-old scored a brace on either side of Juan Mata's penalty.

Mata told BT Sport: "Every time he plays, he scores. In training, he might not touch the ball a lot but he is a finisher and a killer in the box. He is a nice kid and I'm very happy for him."

On his goal: "It's nice and hopefully I can start stepping up with more. I'm happy with the penalty but also the performance of the whole team. It's been a good 10 days but it's another important game against Everton on Sunday."
