Manchester United are reportedly set to enter negotiations with Tottenham Hotspur for Toby Alderweireld with United boss Jose Mourinho not convinced by his options at defence.
The Portuguese boss witnessed the Red Devils concede just 28 goals during the recently-concluded season but he is still unimpressed with his options at the heart of the defence.
As such, the Manchester Evening News claims the Old Trafford club are seeking to sign the defender from Spurs and are set to offer as much as £55m to push through a summer agreement.
The Belgian has unquestionably been one of the most-consistent Premier League defenders over the past few seasons but his future at Tottenham remains uncertain beyond the summer.
The Belgium international started the 2017/18 campaign as the first-choice centre-back alongside Jan Vertonghen but he happened to lose his place to Davinson Sanchez following a hamstring injury prior to the festive period.
On his return in February, the former Ajax graduate struggled to receive the assurance of regular gametime under Mauricio Pochettino and he finished the season with just 13 Premier League starts.
Taking this into regard, Alderweireld has been reluctant to pen a new Spurs contract beyond the summer of 2019 and the club are now considering his sale, given the one-year option on his contract, has a £25m release clause attached to it.
United boss Mourinho has reinforced the central defensive department over the past two seasons with the signings of Eric Bailly and Victor Lindelof respectively but neither have been able to cement a regular starting spot.
