We need 2 CBs.We do not have the centre backs to push up and hold a higher line. We will get slaughtered.
Romero could just about do it, although I wouldn’t trust him. Dier and Lenglet would get eviscerated. So any attempt to play a more aggressive brand of football will require a new CB (ideally a good one).
But most likely Lenglet, Tanganga, Sanchez aren’t here next season
