In the CL final he was awful (but so we're the entire team).
Genuinely thought he was 37 year old Francesco Acerbi on more than a few occasions the way he was left chasing shadows by PSG.
The times I've seen him before that he's been class. Might be the type of defender who does best when play is in front of him, rather then chasing towards his own goal. Which makes him very unsuitable for us.
