There are a few at ‘selling clubs’ like Grimaldo and Telles for a start. I like Grimaldo, he has great attacking qualities, although has his own injury concerns.
Beyond that, I don’t know if a good fee could tempt others. David Alaba is often linked with other top clubs, for example. I’m sure he’s not on the transfer list, but I’d happily pay £60m+ for him, for example, and perhaps that would get it done. Jose Gaya at Valencia is one we could get too. Then of course, there’s Benjamin Chilwell, who will likely move to a bigger PL club in the next 18 months. Digne could probably be gotten too for a decent few.
