Manchester United have triggered the 12 month option in Ashley Young's contract.
The new deal sees Young's stay extended to 2019.
A new longer-term deal could be in the offing if he maintains his good form.
He recently signalled his wish to stay at Old Trafford in an interview with the Mail on Sunday by stating: "I've always wanted to be here and for as long as I can. I'd like to finish my career at United."
