With José Mourinho now at Tottenham, the attention is focused towards how he is going to turn things around at the club.
Improving the defence will be critical, given Spurs have let in 17 goals in 12 games already this season and looked far from assured at the back.
Mourinho is well known for being a manager who prefers the defensive side of the game, having utilised the low block to great effect in the past.
Unlike at Manchester United, he has a good selection of central defenders at his disposal at Tottenham, with Jan Vertonghen, Toby Alderweireld and Dávinson Sánchez all to pick from when he designs his defence.
Nelson Rivas is certainly predicting an improvement from the Tottenham defender, having worked under Mourinho himself during his career.
“He is going to meet an excellent coach, but first of all, with a great person who gives a lot of confidence to the player, especially in the human part,” he told Marca.
“On that side, Dávinson will do very well. He will guide him, he can sit down and talk, and he will improve with him. He’s going to get better. He is very friendly with the players.
“He (Sánchez) is having a great time; he adapted very well to English football, so he will surely have many possibilities to play with him (Mourinho).
“In addition, he is a young player who has many qualities. Mourinho likes aggressiveness, and he has that. With training, he will improve and surely be the starter.”
