Last season’s Premier League runners-up beat several clubs to the highly-rated Colombia International’s signature on Wednesday, agreeing on a transfer fee of £36.5m with Ajax Amsterdam.
The 21-year old may only have spent a single season in Europe since moving from Atletico Nacional to the Eredivisie, but showed enough maturity and class to earn him the Ajax Player of the Year award.
Speaking to reporters ahead of his side’s Premier League clash against Burnley on Saturday, Pochettino admitted that it was the ease with which the youngster adapted to his new environment that singled him out as a target.
“That is what caught our attention with him,” Pochettino said. “When he arrived at Ajax, from the beginning he showed his quality, started to show his character and personality. I think he was the best player for Ajax in his first season. That showed that he is a player with big character and personality, and with a lot of potential.
“When we knew about the possibility to sign him, it was 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,” he added.
“He is so aggressive, so fast, and he loves to play with risk at his back,” Pochettino added, referring to Sanchez’s propensity for joining the attack – a trait that saw him net six league goals for the Amsterdam club last season.
“He wanted to move and to play for Tottenham. Davinson is with us because a lot of clubs were interested in him but he decided to join us. He’s young, but he won the Copa Libertadores with his team in Colombia. And played regularly for Ajax, played the Europa League final against Manchester United.
