Tottenham Hotspur defender Davinson Sanchez has been one of Nuno Santo's best-performing players since the start of the new Premier League season, even if he's recently landed himself in hot water over his international duties.

However, since his arrival in August 2017 from Eredivisie giants Ajax, the 6 foot 2 colossus has seen his value decrease at a very alarming rate.

The 25-year-old was signed for a then club-record £42m and he was soon talked up by former Spurs boss Mauricio Pochettino, who tipped him for some very big things.

It's fair to say that his career has not panned out that way thus far.

"I like his personality and how he is aggressive, he is fast, he will fit for us very well. Davinson is with us because a lot of clubs were interested in him but he decided to join us," he said to Sky Sports.

"It's a massive opportunity because we believe he will be one of the best centre-backs in the world in the future. That is why we made the effort to try to sign him."

Sanchez is now valued at just €20m (£18m) by CIES Football Observatory, meaning in the four years he's been at the club, his total worth has decreased a whopping 57%, which is concerning considering he is yet to hit the peak of his career, particularly as a centre-back.

It's even more shocking when taking into account Pochettino's glowing praise but the reality of the matter is, the Colombian international just has not been good enough since arriving in north London.

Yes, his opening three games this campaign have been majorly positive and encouraging but that's a needle in a haystack compared to the last few seasons.

Back in April, former Republic of Ireland star Kenny Cunningham dubbed the centre-back a "real liability" to his team following Spurs' 2-2 draw with Newcastle, a game in which they threw away three points because of his defensive frailties.

Even more recently he has been getting plenty of stick - ex-Colombia manager Jorge Luis Pinto told ESPN F90 (via Spanish outlet Marca) that the Lilywhites defender "does not have the talent."

Perhaps a little harsh given the £75k-per-week star has been one of Spurs' standout players so far this campaign but it does highlight his previous and long-term struggles at the club.

Overall, chairman Daniel Levy made a big mistake with this transfer, though there is still plenty of time to salvage the decision, especially as he appears to be Nuno's first-choice defender, despite the arrival of Cristian Romero.
