The reports state that Tottenham will have competition for his signature, with Ajax, Benfica, Stuttgart and Schalke 04 all interested, and that his current deal expires at the end of the coming season.
The Nigerian, who is predominantly a left back, was ever-present for AS Trencin last season as they won the Slovakian top flight, and has since played in a Champions League qualifying match against Steaua Bucharest. However, he was unable to stop the Romanian side storming to a 2-0 victory.
Should Tottenham look to sign Kingsley this summer or risk waiting and getting him for free for next season?
Although the young defender is clearly a talented prospect, Mauricio Pochettino boasts arguably the biggest selection of full-backs in the Premier League.
Kyle Walker, Danny Rose, Jan Vertonghen, Vlad Chiriches, DeAndre Yedlin, Eric Dier, Ben Davies, Toby Alderweireld, Kevin Wimmer and Kieran Trippier have all played in a full-back position at some point in their career, on one side or another, even if it isn't their prefered position.
With regards to Kingsley, Pochettino has the the ability to watch the situation closely in an attempt to try and sign him once he is released from his current deal next season.
The 19-year-old, if he was to sign, would be a working progress at White Hart Lane anyway, so another year of first-team football in Slovakia makes sense as it could help him develop further than he would in the U21 Premier League.
