There have been reports in the British media that the French striker has grown tired of his lack of first-team football under Jose Mourinho this season.
Martial has made only nine Premier League starts for Manchester United so far this season after struggling to find consistent form under new boss Mourinho at Old Trafford.
However, the French striker used his personal Twitter account to deny claims that he is unhappy at Manchester United on Monday morning.
Dont listen the papers it's wrong thanks Come on United 🔴

Manchester United are currently in sixth place in the Premier League table after their 3-0 win over Leicester City at the King Power Stadium on Sunday afternoon.
The Red Devils are looking to break back into the top four this season after they finished fifth and won the FA Cup under Louis van Gaal last season.
