We have seen a rapid increase in loan deals that often have an option to buy included in there, but if a player is really in favor, it will always be preferable to sell them on a permanent basis.
Barcelona have a situation at left back where Jordi Alba is still good for a year or two, but injuries will catch up with him, while Junior Firpo has simply not developed into a possible successor as they hoped.
Firpo is a good La Liga player, but he is not good enough for Barcelona, and that means an exit is likely this summer.
A report from Football Italy has indicated that West Ham and AC Milan will both sign him in this window, but the Hammers are in a stronger position because they can afford to buy him directly.
Milan want a loan deal before the situation is reviewed next summer, but Barca prefer to just move him on, while a move to West Ham should be more attractive as he gets a fair chance to push for a place instead of being backed up again. en Theo Hernandez is not being dropped by the Italian giants.
Milan actually offer Champions League football and it can always tip the balance in their favor, but a switch to the Premier League looks like the more likely option here.
