Tottenham are launching a bid for Ajax defender Davinson Sanchez.

The Sun says Spurs have targeted Ajax's £35million-rated brilliant young Colombian defender Sanchez as their first summer signing.

Mauricio Pochettino has yet to break out Spurs chequebook this summer despite pocketing a hefty £50 million following England defender Kyle Walker's move to Manchester City.

However, talks have begun in Amsterdam with Ajax over a deal for the twice-capped 21-year-old who was the Dutch giants' Player of the Year last season and their star performer in their Europa League cup final defeat to Manchester United.

Spurs can expect stiff competition from Chelsea, Barcelona and Crystal Palace, whose Dutch boss Frank De Boer, managed Ajax and knows all about the youngster's quality.
