Former Manchester United defender Mikael Silvestre is backing their move for Atletico Madrid star Antoine Griezmann.
His advisor Eric Olhats this week revealed that initial talks have already taken place ahead of a potential deal.
And Silvestre told the Manchester Evening News: "You need a lot of energy now in the modern game - Antoine has that.
"He has a lot of talent. He has got the right attitude. He would be perfect for United.
"The fans would love him. His stamina, workrate, his finishing. It would be a great signing for Manchester United.
"In my time we had Andy Cole, Dwight Yorke, Ole Gunnar Solskjaer, Teddy Sheringham - proven goalscorers. Ruud van Nistelrooy - proven goalscorer. Louis Saha - proven. Wayne Rooney - proven.
"That's what you need. It is a priority.
"Marcus Rashford and Anthony Martial are not regular 25-goals-a-season players yet. They have some time to go to be that kind of a player who will produce week in, week out.
"You need someone like Antoine. Manchester United need him. Someone you can rely on to produce consistently. At 26 he is the right age and has a proven goals background."
