Tottenham are chasing Valencia pair Shkodran Mustafi and Sofiane Feghouli. The Daily Star says Spurs scouts have watched both players extensively in recent weeks and were present last weekend as Valencia beat Elche 4-0.
Mustafi, who spent three years at Everton earlier in his career, is under contract until 2019 while Feghouli is a free agent in June 2016.
Valencia do not want to let either player go next summer but may have to sell to fund a spending spree of their own.
