Tottenham Hotspur could make their first signing of the summer as The Sun reports they lead the race to take Davinson Sanchez away from Ajax.
However, the Dutch club value the Colombia international at around £35 million, which may prove to be a stumbling block.
The report claims Spurs chairman Daniel Levy is prepared to offer £25 million for the centre-back and that talks are already underway over a transfer.
It is one of the key areas of the squad that Mauricio Pochettino wants cover for.
If Kevin Wimmer makes a move away from the club, it would leave Spurs with only Eric Dier and youngster Cameron Carter-Vickers as back-up for Jan Vertonghen and Toby Alderweireld.
Tottenham could face competition for the 21-year-old – who impressed during Ajax’s Europa League final defeat to Manchester United last year – from Barcelona, Chelsea and Crystal Palace.
But The Sun claims that Spurs are in pole position to sign the defender, who has made 44 appearances for the Dutch side since a £4.5 million move from Atletico Nacional last summer.
The London-based club remain the only Premier League side not to have landed a transfer this summer, and a number of potential deals have fallen through – much to the frustration of fans.
Despite selling Kyle Walker for a fee of around £50 million to Manchester City, Levy refuses to pay over the odds or be rushed into making signings.
Whether that policy will have to change as the end of the transfer window gets closer remains to be seen, but The Sun claims talks with Ajax have begun.
His ability to also play at right-back makes him an ideal target following Walker’s departure and Tottenham’s failure to sign a replacement.
However, Wimmer could yet remain at the club, particularly if Spurs do not sign another centre-back.
His agent claimed earlier this summer that Spurs are pricing him out of a move, demanding other clubs meet their £20 million valuation of him.
Tottenham have close links with Ajax, with Spurs signing Christian Eriksen and Jan Vertonghen from the Amsterdam giants, while Toby Alderweireled also can count the Dutch club among his former employers.
