But Lampard has questioned why Man Utd splashed the cash on Mount, who he worked with at both Chelsea and Derby, because the Red Devils already have Bruno Fernandes.

Lampard said: “The only worry I had with him when he went to United was where do Bruno Fernandes and him fit? Bruno is the captain of the football club, plays in the same position and hardly gets injured.

“Then have Casemiro. I know it’s starting to develop already and change away from that as an idea, but you could kind of think, where does he fit?

“This is not to dig Mason or Man Utd actually for bringing him in, but for a player of that level and for that money, you have to go, ‘This is the plan’.

“That’s what I would want to hear. My question would be, where does he fit?”

Injury-plagued Mount has made just 12 appearances for Erik ten Hag’s struggling side with his last outing on November 11.

Yet even when he was fit he only made seven starts and is yet to score for United.

Mount is closing in on a return to first-team training and Lampard told the Stick to Football podcast: “He’s had injuries, he’s in a team that is struggling and there’s big negativity in certain ways.

Mount has spent much of this season sidelined with injury

“I’m not saying it because I’ve had a relationship with him in terms of managing but I do think he will come good because of his talent.

“Once the team gets more structured, because I do think it’s important to say you’re an aggressive eight or a 10.

“It’s a difficult one and a conundrum for the team to get him into the team in his best position.

“He is very driven and if you drop him the face goes and not in a bad way, he will want to show you. He is very determined.”
