The Spurs defender could have an impact similar to Virgil Van Dijk's at Liverpool.
Manchester United have had a busy start to the summer transfer window, bringing in defender Diogo Dalot from Porto for £19 million and agreeing a fee of £52 million for Shakhtar Donetsk midfielder Fred.
The two signings show Jose Mourinho’s desire to sure up the side defensively and it appears the Manchester United manager isn’t finished yet.
According to the Sun, Mourinho was determined to finalise the signing of Toby Alderweireld from Tottenham Hotspur before the World Cup began in Russia on Thursday, but unfortunately for him, that hasn't happened.
The Sun report claims that United are willing to pay the £50 million Spurs are asking for, as long as the deal is structured right.
Manchester United should make signing the Belgian their main priority, as it would give them something they have lacked since Rio Ferdinand and Nemanja Vidic retired - a top-class centre-back with Premier League pedigree.
Alderweireld joined Spurs from Atletico Madrid for £11.4 million in July 2015, after impressing on loan at Southampton in the 2014/15 season, and has been an excellent defensive asset since.
United have recently opted to roll the dice and bring in young defenders from outside the Premier League, none of whom have managed to lock down a starting place.
Alderweireld represents a much safer bet for the Red Devils and given his leadership qualities and ball playing ability his impact could be similar to that of Virgil Van Dijk, who has improved the Liverpool defence hugely since joining in January.
