Manchester United have triggered a one-year option in Anthony Martial's contract.
The Frenchman is now under contract until 2020, however, the club have begun negotiations to further extend that deal.
Martial is United's top goalscorer with eight this season and has established himself as a regular starter after previously falling out with manager Jose Mourinho.
Juventus, Chelsea and Tottenham have all expressed an interest in the 23-year-old.
However, Goal claims Martial is open to remaining at Old Trafford beyond 2020.
