Manchester United are believed to have triggered the 12-month extension in Anthony Martial's current contract to tie him to the club for another year until 2020.
Martial was due to be out of contract at the end of this season and could theoretically have started to discuss a potential pre-contract agreement with overseas clubs as soon as January. But United have prevented that from happening and remain intent on a longer term deal.
Although not publicly announced by the club, the news about the Frenchman's contract emerged on Monday afternoon and was reported independently by BBC Sport, the Manchester Evening News and Evening Standard at around the same time.
