But Ajax have offered Sanchez a huge new deal worth £54,000 a week to stave off Tottenham's interest in the Colombian centre half.
Sanchez was hugely impressive in his debut campaign in Holland last season as he made 43 appearances to help Ajax finish runners-up in the Eredivisie to title-winners Feyenoord.
Davinson Sanchez had an average pass accuracy of 89% in the Eredivisie last season.
Tottenham finally got into some transfer action this week after it emerged that they have slapped in a €38.5m bid for Ajax's 21-year-old defender Sanchez. In fact, the youngster also scored with six goals and provided two assists. Move to Spurs imminent?
Ajax's road to the Europa League final was partly paved by the valiant efforts of Sanchez. Additionally, his reading of the game is quite mature - a skill that Pochettino is likely to appreciate.
Sanchez is also at the age and experience level that makes sense for Spurs - he has enough of a track record for Spurs to believe that he could be a reliable backup, but he's young enough that he won't expect to be first choice right away.
As Sport Witness explained at the time, Ajax's "not for sale" didn't really seem like the final answer, and it nearly felt the Dutch club were fishing for better offers, whether they be from Tottenham or elsewhere.
Kyle Walker departed the club this summer to join Manchester City for £50 million and Spurs have not brought in a replacement as of yet.
Barcelona, Real Madrid and Inter Milan have all been linked with a move for Sanchez, who is valued at upwards of £35m by Ajax, but Spurs could be in the driving seat given Mauricio Pochettino's reputation for helping youth to flourish.
