Former Serie A striker Alessandro Matri says Romelu Lukaku is now struggling with AS Roma.

Matri insists Lukaku must change his style to succeed with coach Daniele de Rossi.

He said on DAZN: "With (Antonio) Conte he made the difference, he relied a lot on him.

"De Rossi at Roma he plays differently, with constructed actions. I think the player must also change the way he plays, he can't just play with his back to goal and then turn around, he must be physically and mentally strong.

"But I haven't yet seen the Lukaku who dragged Inter and who he had resourcefulness."
