Juan Mata says Manchester United teammate Paul Pogba is one of the best players in the world.

Pogba scored and assisted in United's 2-0 win over Chelsea in the FA Cup fifth-round on Monday night.

"Yes, he assisted the cross for the first goal, scored the second one. Even in the second half, 80, 85 minutes he was still defending, going forwards," Mata said.

"He's very, very complete. He's got physique, he's got quality, he's got a pass, he can go box to box.

"He's one of the best. Today he showed why."
