The rumoured player is the 31-year-old defender Inigo Martinez and Barcelona are thinking of making the move in January. He is actually a regular player in Athletic Bilbao's starting eleven now. However his contract is expiring next summer as well. I don't think that it would be difficult for Barcelona to convince him to sign for them in this condition. Pique's annual salary is €29.5m as far as I know. After his retirement Barcelona want to take advantage of the financial relief to go for Bernardo Silva but I don't think they'd get a positive answer from Manchester City.

I don’t think that he is a top-class defender, to be honest. He is good but not up to the standards that maybe some Barcelona fans expect him to be.
Yes, he is already 31 years old. But at the same time, I also get why Barcelona wants to sign him.
He’s not going to cost a lot of money which Barcelona doesn’t have right now. And with him the money that Barcelona is going to spend, I think they will get a decent amount of performance. But I don’t think Barcelona will be able to defeat teams like Real Madrid with this type of defense.
