Darwin Nunez has been linked to joining Manchester United this summer.
The Uruguayan forward has had a phenomenal season with Benfica and only Lewandowski has scored more goals than him in Europe.
Both Manchester United and Arsenal linked with the striker and former United forward Diego Forlan has urged Nunez to snub Arsenal and join Man United instead.
Forlan told Breaking the Lines: “I think that he is a very good player, a good kid who is doing really well at Benfica and is enjoying a strong season. It is not just the Portuguese league where he is doing well but in the Champions League too, where he scored six goals this season and helped take Benfica to the quarter finals.
“He is a player who has a lot of potential and he could fit in at Manchester United. But obviously, everyone needs to have patience, although he is getting better with more and more experience.
“He would not be a bad signing for Manchester United and it would be nice to see him there. It is a club that gives you time, that makes you feel comfortable and as if you are in a familiar place, very cosy and nice. It would be spectacular having him playing for Manchester United.”
