Agent Giocondo Martorelli expects Fiorentina to sell Sofyan Amrabat this summer.
The Morocco international is a confirmed target for Manchester United.
Martorelli told Radio Firenze Viola: "There were already possibilities after the World Cup in January, an extraordinary showcase. The attention on this player is real and I don't exclude that, by continuing to do well and if Fiorentina were to reach an objective in Europe, even more prestige could come and an important offer.
"In that case, Fiorentina must take him into consideration: unlike in January, there will be the possibility of having identified a replacement, someone who can even improve them.
"The transfer men will already be evaluating it."
