Laporte would be so perfect for us it still drives me crazy that he backed out of the deal. There's a lot of different players we could look at though.
Yerry Mina is interesting because he's 23 but still in Brazil, not sure if Pep and the board would want to bring him over without a loan to Girona or somewhere else first. Skriniar and Koulibaly would both cost a decent amount and Koulibaly is 26 (not that 26 is old, but there are younger options).
Tah I think will be off to somewhere if he receives attention from the big clubs. Leverkusen have been shite this season. Ginter is versatile which Pep would like. I really rate de Ligt but if we signed him we'd defo loan him somewhere for at least a season (he's still only 18), which I'm not sure he'd be thrilled about.
So much talk about Lucas Hernandez and I for one would be very pleased with that. Still only 21 and he and Stones could be our CB partnership for a decade.
Mangala will be off, but I think he'll stay until the summer with Vinny's injury problems. Then comes the question of whether or not Vinny will be in the team next year (whether it be he or Pep's decision).
Alexis seems to be a formality, which means CB and pivot are the positions we should expect to make some new signings.
