Davinson Sánchez (€40 million) (20/20)

Davinson Sánchez arrived in Amsterdam for five-million Euros in summer 2016, shortly before winning the Copa Libertadores with Colombian outfit Atlético Nacional – just the second in club history. Upon his arrival, Sánchez slid seamlessly into the side, taking little time to announce himself as their most important player.

A physical specimen, he is virtually unbeatable in the air, as evidenced by the six goals he scored in his first – and only – Eredivisie season, tied for the league lead amongst defenders with PSV’s Hector Moreno, bought by Roma earlier this summer. Sánchez started 32 of 34 Eredivisie matches with Ajax, missing only their first game due to the timing of his arrival, and their penultimate league clash as he was rested for a midweek European tie. In the Europa League, he played a crucial role in guiding Ajax to their first European final since 1996, playing every minute of the knockout stage (minus one match missed due to suspension), helping them to three clean sheets.

While his time in Amsterdam was short-lived, Sánchez has etched his name into Ajax – and Eredivisie – history. His sale to Tottenham of 40-million Euros (which could rise with add-ons) is an Ajax and Eredivisie record, surpassing the 34 million Manchester United spent to buy Memphis Depay. It’s a higher fee than was paid for the likes of Ruud van Nistelrooy, Wesley Sneijder, Klaas-jan Huntelaar, Luis Suarez, Arjen Robben, Dirk Kuyt, Zlatan Ibrahimovic, Christian Eriksen and so many others.

Sánchez completed just under 90 per cent of his passes in his only season in Amsterdam (88.9), the third-best mark in the Eredivisie. In the Europa League, many of Sánchez’s numbers saw drastic increases, proving his ability to step up his game against improved competition. His total tackles per match almost doubled, and his average completed dribbles, interceptions and key passes were higher.

The Colombian centre-half is a stalwart in defence. Built like a mountain, Sánchez has every tool to become a world class defender. Those who have watched him over the course of the last year might argue he’s already flirting with the label. At the ripe age of 21, he plays well beyond his years. Aggressive in his approach, Sánchez mimics a concrete wall in the centre of defence and has become famous for the impeccable timing of his last-ditch challenges.

At Tottenham, he joins the likes of Jan Vertonghen, Christian Eriksen and Toby Alderweireld – all members of this list.
