The 21-year-old took home the Man of the Match award on our Official App, with 81% of your vote, and the Spaniard highlighted the way James attacked from the left-hand side.
“[It was a] very good goal, a fantastic finish. He’s a very hard-working player,” Mata told MUTV after the final whistle.

“[I’m] very happy for him and hopefully he can do it many more times.
