Negotiations between Manchester United and Tottenham over a deal for Toby Alderweireld have reached an impasse.

Jose Mourinho remains confident he can sign the Spurs centre-half Toby Alderweireld but talks are deadlocked with Spurs asking for in excess of the £55m fee United thought would seal the deal.

United's position is strengthened by the fact Spurs are keen on Anthony Martial, who has become unsettled at Old Trafford under manager Mourinho.

Martial made just 18 League starts last term and Tottenham's interest could help the clubs reach a compromise.

United are already prepared to hand Alderweireld a five-year contract and a salary far in excess of Tottenham’s last offer of around £120,000 a week.

Spurs are ready to sell the 29-year-old Belgium star for the right price. His contract expires in 2020 but the defender can leave for just £25m next year if no fresh terms are agreed.
