4. Daley Blind
Ajax has proved a happy hunting ground for Spurs, with both Jan Vertonghen and Christian Eriksen proving Premier League class at a reasonable price. The North London outfit should look no further than the Eredivisie club in their search for a new left back this summer. Dutch international Blind, 24, is enjoying a cracking season for Frank de Boer’s side and will be the Netherlands’ first choice at this summer’s World Cup. Danny Rose could remain as a back up but hasn’t proved himself worthy of a regular starting spot.
