I think Sanchez has been a bargain for Spurs. With Alderweireld missing most of the season I think he's done well alongside Vertonghen, they sit 3rd with a Champions League place guaranteed. Maybe if Chelsea had replaced Terry with Sanchez they might be in the top 4?
The Van Dijk transfer has muddied the waters in terms of market rates for centre backs because Liverpool got fleeced for the bulk of their Coutinho cash by Southampton. I fancy Liverpool paid £15m over the odds for VVD.
I think Spurs got a better deal with £42mill for Davinson Sanchez...
