Looked more than ok tonight, maybe not perfect but may well improve once he gets to play more with his Spurs team mates - much better than expected given his relatively low price, although that may have been affected by rumours of failed medicals. Reassess after a few more matches, but likely to be one of the best defenders available this window and a decent squad player at worst.
Looks like Roma (following on their abortive purchase in summer), Wolves and one or two other clubs thought they had signed him until just before we did, which may slowed the buying process down.
