And the iconic centre-back is confident Amorim should switch to a 4-2-3-1 formation.

Ferdinand said on his Rio Presents podcast: “If they played 4-2-3-1, I think you’ve got all the players playing in positions that they’re super comfortable in.

“You’ve got two central midfielders out of three probably in Casemiro, [Manuel] Ugarte and to play in there.

“And then you’ve got three across the front, anyone from Amad [Diallo], [Bryan] Mbeumo, [Matheus] Cunha, Mason Mount – even Mainoo.

“All of them and Bruno [Fernandes] can all play in them positions anywhere across that front line. And they’re all happy as Larry anywhere.

“And [Benjamin] Sesko up front, but you’ve got Bruno who actually can be in the ten role where he has produced astronomical numbers consistently since he’s been at the football club.

“That I don’t think is rocket science. I just think everyone’s probably looking at it and thinking the same thing.”
