According to various reports, Tottenham are very close to finally completing their first signing of the summer.Mauricio Pochettino is expected to smash the club transfer record with the £42m acquisition of Ajax defender Davinson Sanchez.The 21-year-old Colombian international joined the Dutch giants in a €5m deal in 2016 and has quickly earned himself a reputation as one of the finest defenders in Holland.Sanchez is a versatile centre-back that can also operate at right-back.Spurs sold Kyle Walker to Manchester City for £50m earlier this summer and fans have been begging for Daniel Levy to bring in some more cover for Kieran Trippier.Sanchez has only played one season in European football and he'll have plenty to do in order to prove himself in the Premier League.One man who recently claimed to know a thing or two about the Ajax star is Manchester United manager Jose Mourinho.The Portuguese tactician was quoted earlier this summer suggesting he isolated the young defender in the Europa League final because of his weakness in possession.

As reported by Tribuna Expresso, the former Chelsea and Real Madrid boss told students at the University of Lisbon:

“We let them go out to play, but blocking the right center, De Ligt, and letting the ball go to the left, Sánchez, who had more difficulties.”

Manchester United, targeting Sanchez as a weak link, ran out comfortable 2-0 winners over Ajax in the Europa League final.

Argentine Spurs coach Pochettino is renowned for his attractive style of football and has drilled Jan Vertonghen and Toby Alderweireld to play out from the back.

If Sanchez does indeed struggle on-the-ball, you would imagine that he would struggle to make an impact under Pochettino in North London.

Austrian defender Kevin Wimmer is being trailed by West Brom and could be allowed to leave if the Lilywhites complete the club record signing.

Spurs kicked off their 2017/18 campaign with a 2-0 win over Newcastle United but welcome rivals Chelsea at their new temporary home on Sunday afternoon.

Wembley has not been a happy hunting ground for Tottenham in recent years and they'll be hosting 19 Premier League fixtures at the famous London ground this season.
