Manchester United winger Memphis Depay has revealed that he "went crazy" when he was substituted against his former club PSV Eindhoven last month.

The 21-year-old started the Champions League group encounter, which ended in a 0-0 draw, but he was replaced shortly after the restart by Ashley Young.

Speaking about that moment, the Dutchman told AD: "The most difficult moment was when I got substituted against PSV at Old Trafford.

"That hurt a lot. I wanted to perform against my former club and then I got substituted after one half already.

"Yeah, I went crazy. Angry, too. At the same time, anger like that doesn't block me. It's just helping me. I will be better eventually, I know that."

In the same interview, Depay also admitted that he is determined to become the best player in the world.
