#3 Tottenham Hotspur - Toby Alderwereild

Toby Alderwereild had a disappointing season with Tottenham Hotspur in 2017 and he was set for a move in the previous transfer window. Though he was linked to multiple clubs, none of them materialized and the Belgian had to stay back at the club. Spurs have activated the option to extend Toby's contract but he has still got many suitors across Europe.
Manchester United are in the worst possible defensive crisis right now as most of their defenders are injured and few of them are not performing well. Hence, to become a world-class team, the Old Trafford club needs a few defensive reinforcements and Alderwereild will be a perfect addition to the club.
Alderwereild is a strong center-half and can also double up as a right back. His attacking instincts would be useful for the team too. United lack a towering presence in front of De Gea and Toby could fulfill that very easily.
