Manchester United are ready to trigger Toby Alderweireld's £25million release clause this summer.
Tottenham chose to extend the centre-back's contract by an additional year in January but it meant the inclusion of a release clause this summer.
United have long been interested in the 30-year-old and are ready to pay the fee, according to the Sun.
Talks between Alderweireld's representatives and Spurs broke down over a fresh long term deal and Mauricio Pochettino is confident in Davinson Sanchez combining with Jan Vertonghen next season.
