Anthony Martial is reportedly facing a battle to save his Manchester United career.
Martial was strongly linked with a move away from Old Trafford in last summer's transfer window, but the club refused to sell the Frenchman, who ultimately penned a new long-term deal at the end of January.
The 23-year-old has scored 12 times in all competitions during the 2018-19 campaign, but has not featured in United's last two Premier League matches after struggling for form in recent weeks.
According to the Daily Mail, both Ole Gunnar Solskjaer and assistant manager Mike Phelan have 'grown increasingly frustrated' with Martial's attitude and as a result, the attacker is facing a battle to save his career with the 20-time English champions.
Martial - a 2015 arrival from Monaco - has scored 48 times and contributed 29 assists in 173 appearances for the Red Devils in all competitions.
United, who can no longer finish in this season's Premier League top four, will end their 2018-19 campaign at home to Cardiff City this weekend.
