I think Koulibaly is excellent but I believe City are making the right decision to not be extorted by Napoli again, if true
Pau Torres is left footed, seems an unlikely target. Diego Carlos & Monchi will be difficult to negotiate down, even for Txiki which makes me wonder whether Skriniar is an option. The Slovak is happy at Inter but there are rumours he is on the market, much to the disappointment of Interisti - but while an excellent 1v1 defender, he is not your prototypical central defender on the ball for Pep
For me, I would prioritze Söyüncü
