Ralf Rangnick has revealed he blocked Anthony Elanga from leaving Manchester United after watching his highlights on YouTube.

In his second consecutive start, the Swedish teenager scored the opening goal against Brentford as United ran out 3-1 winners.

"I must say from the very first day from my first training session, he showed up," Rangnick told BBC Sport.

"l had heard his name before and I was in my hotel room watching videos of him on YouTube, I thought this boy was really good.

"He was almost on his way out on loan, I told him you will not go out on loan, you will say here. He has developed in training."
