Kongolo has been on Manchester City’s radar for a number of months, and they hold an advantage over other clubs having already signed Kongolo’s younger brother Rodney.
The 20-year-old has been a vital part of the Feyenoord side who have been performing so well in the Eredivisie this season, playing in 12 of 14 games in a defence that has conceded just nine goals - the lowest in the Dutch top flight.
He enjoyed a remarkable rise to fame in 2014, and his current good form is just the cap of the year that saw him called up to Louis van Gaal’s Netherlands squad for the 2014 World Cup, and, although he registered just one minute of substitute action during the tournament, his inclusion at such a young age has shown his real promise.
His younger brother Rodney has already made the switch to England than many are expecting of Kongolo in the future, and the 16-year-old - who has been compared to Patrick Viera - could hold the key in Manchester City turning their interest into a concrete offer for the young centre-back.
However, Kongolo’s incredible form has seen a number of other clubs take notice of him, and Dutch media outlet Voetbal International has reported that City’s Premier League rivals Chelsea, as well as Bundesliga side Borussia Dortmund, are keen on signing the defender next summer before loaning him back to Feyenoord to aid his development in a side where he is guaranteed first-team football.
He extended his contract last summer until June 2017, and the twice-capped international has previously turned down offers of leaving the Netherlands, with Southampton one of the highest profile clubs tracking him previously.
Previous reports have indicated that the 20-year-old could be available for as little as £3 million, and a price that low should have a number of clubs fighting for his signature come the opening of the transfer window.
