#2 Toby Alderweireld

Toby Alderweireld has undoubtedly been one of the best centre-backs in Europe in the past couple of seasons, though, his reputation has taken a hit after being sidelined due to an injury for the majority of this season. The Belgian is a true leader at the back and has been a stalwart for Tottenham Hotspur in recent years.
His game-awareness, combined with an assurance during challenges and strong aerial presence helps Spurs, who have formed one of the strongest defensive units in recent times. Alderweireld can build the play from the back and does not dive into challenges until required. His physicality helps him deal with physically strong forwards with ease. Moreover, he has garnered Premier League appearances in abundance and is in the peak years of his career.
A move for him would add more stability to Manchester United’s backline, however, they need to act soon and take advantage of his contractual negotiations, otherwise Daniel Levy would play hardball, as is his characteristic.
