Manchester United's third bid for midfielder Mason Mount remains on the table, but the club are looking at alternatives after becoming frustrated with Chelsea's approach.
United made a third offer worth an initial £50million for Mount last week, with a further £5million due in add-ons, but Chelsea have now rejected every bid for the 24-year-old, who is out of contract next summer.
The Blues are holding out for £65million for the England international and have told United they would accept £58million, with £7million in add-ons.
They have also suggested holding face-to-face talks to try and resolve the impasse. But United have consistently said they have a limit when it comes to signing Mount, who wants to join the club and could leave Chelsea for free next summer.
