Marseille boss Benatia believes Greenwood has potential to match ex-teammates Robben and Dybala

The ex-Manchester United striker has been exceptional for OM since joining in the summer.

Benatia told BeIN Sports: "Mason Greenwood? That's the very, very high level. I played with (Paulo) Dybala, (Arjen) Robben... he's a player who has no limits. 

"He can score 20 goals per season if he wants to."

He was also full of praise for Tottenham loanee Pierre-Emile Hojbjerg, whom he knew from Bayern Munich.

"He's one of the first names we tried. It wasn't possible at the beginning, I always wanted to relaunch the file, he improves  other players."
