Jose Mourinho is unhappy with Anthony Martial and the forward's future at Manchester United beyond the summer is uncertain, Sky sources understand.
Mourinho has made it clear he has plenty of options in wider positions with Marcus Rashford, Jesse Lingaard, Henrikh Mkitaryan, Ashley Young having all been utilised in those areas this season.
United are also expected to bolster their attacking options in the summer, which would raise serious questions about the future of a player who has scored just two Premier League goals in the current campaign.
Martial, meanwhile, is understood to be happy at Old Trafford and does not want to leave the club.
Reports had suggested the French star is unhappy at recent criticism from Mourinho, who was disappointed with the 21-year-old's performance against Liverpool and left him out of the matchday squad for Wednesday's EFL Cup semi-final defeat to Hull.
While Martial will remain at United this month, his future in the next transfer window is far less certain unless he starts to deliver what his manager is asking for.
Earlier this month, it was claimed by Martial's agent that Sevilla were interested in taking the player on loan but the move did not materialise.
Martial became the most expensive teenager in football history when he joined United from Monaco for an initial £36m in September 2015.
He made an instant impact for United, scoring a superb solo goal on his debut in a 3-1 victory over rivals Liverpool at Old Trafford.
Martial continued to impress during his debut season in England and helped United win the FA Cup in May - their first major trophy in three years - with a 2-1 victory over Crystal Palace at Wembley.
