Some good, plenty of bad.
Fantastic composure and ability to play out of pressure with the ball, very aggressive and combative, will win a lot of duels, great attitude and in a dominant team he will be a superb ball winning CB keeping attacks going but he needs to adapt to the pace and physicality of the PL.
Welbeck gave him, and Maguire, a bit of a chasing for the first hour, held up the ball superbly and then spun behind to great effect. A high line with 2 players in Maguire and Lisandro who both lack top end recovery speed is going to cause issues. Should have given away a pen for the barge on Welbeck, another one in the long list of dubious VAR nonsense.
Still, first game, like a lot of what I saw.
