Former Chelsea manager Frank Lampard has questioned Manchester United's signing of Mason Mount.

The ex-Blues midfielder knows what it takes to play as a box to box no.8 in the Premier League.

While Lampard admires Mount, having brought him into the Chelsea first team, he is not sure how he fits in at United.

Lampard told the Stick to Football podcast: "The only worry I had when he went to Man United was, where do Bruno Fernandes and him fit?

“You've also got Casemiro, and I know it's starting to develop and change away from that already as an idea, but you kind of go: where do you fit?

“And I think when you are – and this is not to dig Mason or Man United out for bringing him in – but I think when you get a player of that level for that amount of money, you've got to go: this is the plan. That's what I'd want to hear, and my question would be: where does he fit?"
