#3 Toby Alderweireld
Alderweireld joined the Spurs side in 2015 from Atletico Madrid. Since then, he has established himself among the elite group of defenders in the business.
The Belgian has been in sensational form over the past couple of years. Alongside Jan Vertonghen, he formed a centre-back partnership which appeared to be unbreakable.
However, the 2017/18 season has been an injury-hit one which has restricted him to just ten league appearances.
According to some reports, the defender is unhappy at the London club with his contract terms. He has demanded a wage-hike which chairman Daniel Levy is reluctant to meet.
The player will enter into the final year of contract next season and this could force Spurs to sell him for a significantly reduced fee.
Manchester City has been linked with a move for the player recently and the 29-year-old would be a quality addition to the defence in place of perennially injured captain Vincent Kompany.
