As Manchester United close on the signing of Angel di Maria, a move for Juan Cuadrado hangs in the balance.
Barcelona are themselves weighing up whether to meet Fiorentina's heavy £40 million asking price for the Colombian international, and the winger admitted over the weekend he has no idea where he will be playing his football from next month.
If a big bid comes in, Fiorentina have a big decision to make, even if it is below what they want to receive. If they decide not to accept it, they could come to regret it.
That is the view of former Serie A coach Serse Cosmi, who has managed Lecce and Perugia in Italy's top flight.
He told Italian news outlet Radio Sportiva: "When they get proposals from teams such as Barcelona is very difficult for a player to say no.
"Fiorentina aims to keep him but some problems may arise even from the point of view of the motivations of the player himself who could stay in Florence reluctantly, having to give up to the chance to get on the train that passes once in a lifetime."
The notion that a move now is a once in a lifetime opportunity for Cuadrado could be especially apt regarding Barcelona.
The Catalan club have a transfer ban which comes into effect once this one closes and they will be unable to sign players until 2016.
There is a chance United could move for the Colombian international in the future, but Fiorentina are even less likely to want to sell mid-season.
United can potentially however take advantage of the fact that Cuadrado may be unhappy if Fiorentina reject a lower offer than they want, and try to work on the fact the Italian side may have to take what they can get, or risk having an unhappy player on their hands.
