Tottenham - Left-back
Andre Villas-Boas had a largely fruitful transfer window but he obviously has little trust in his specialist left-backs Benoit Assou-Ekotto and Danny Rose.
Jan Vertonghen has been filling in much of the time but he is a brilliant centre-back and would improve that area by moving inside.
Fabio Coentrao at Real Madrid is available and nearly made a deadline day switch to Manchester United, but Villas-Boas may be able to convince his compatriot to choose White Hart Lane in January if Spurs's good form continues. The Portugal international would be a step up in quality in that part of the pitch for Tottenham.
