The Belgium international’s current deal expires in 18 months, although it does include a one-year extension that can be triggered in 2019, but the 28-year-old has delayed putting pen to paper over fresh terms.
Manchester City and Chelsea are both keen to sign the former Southampton centre-back, should he decide to move on, and Jose Mourinho is now contemplating a deal for him, according to the Manchester Evening News.
Though Mourinho has spent big on centre-halves Eric Bailly and Victor Lindelof during his short spell at Old Trafford, his defence is still a cause for concern.
And he believes Alderweireld would be a fine addition.
Mourinho has failed with previous moves for Tottenham stars, with Danny Rose and Eric Dier both former targets, however, the short amount of time left on Alderweireld’s contract may force Spurs’ hand.
Should United not complete a deal this summer, Alderweireld has a £25million release clause that comes into effect in the summer of 2019, which would be seen as a bargain move for a player of his stature in the current market.
