According to Foot Mercato (via GFFN), Tottenham Hotspur are in constant contact with the representatives of West Ham United centre-back Issa Diop as they eye a summer move. Spurs boss Jose Mourinho is a fan of the Frenchman, and player himself appears keen on moving to North London having recently spoken with right-back Serge Aurier about the club. The Hammers believe that Diop is worth £60 million, but a bid of around £52 million could be enough to tempt them into parting ways with him this summer. Tottenham are yet to table a formal bid for the 23-year-old, but a move appears to be on the cards with the future of Belgian defender Jan Vertonghen at the club not certain.
