PSG coach Thomas Tuchel admits they're worried facing Manchester United's French duo Anthony Martial and Paul Pogba.

Tuchel believes his side face one of the biggest challenges in football by trying to overcome a resurgent United in the last 16 of the Champions League.

“I don't think there's any surprise about Paul Pogba being a key player," said the German. “He's an incredible player, wonderful qualities. He can do a lot of things - extremely strong with the ball at his feet, he's very good and very strong in challenges and one-on-ones.

“Taking people on, he's always capable of making a difference and I think in my opinion he's always dangerous offensively with (Anthony) Martial. They're a very dangerous pairing.

“Pogba is dangerous in the penalty area as well when the ball comes in from the right and he arrives at the right time, he's a very good header of the ball. He's a key player absolutely and he's now becoming a leader.

“He loves playing for this club."
