Everything has been quite rosy at Manchester United over the last few weeks.
They have won their first two games of the season, broken the world record by re-signing Paul Pogba and under Jose Mourinho, look like they are on the verge of becoming a dominant force in England again.
So the Man United manager should be feeling pretty pleased with his players, right?
Not quite. While Zlatan Ibrahimovic, Paul Pogba and even Wayne Rooney have earned praise for their performances, Anthony Martial has struggled to replicate his form from last season.
The Frenchman was United's top scorer and Louis van Gaal's key man during 2015/16 but was ineffective on the left flank in both matches against Bournemouth and Southampton.
And according to The Sun, Mourinho has warned the 20-year-old he must improve to stay in the starting XI.
There have been a lot of reports regarding Martial's personal life flying around over the last few weeks and his manager is concerned they have affected his performances on the pitch.
He has been substituted in both Premier League clashes to date and given the fierce competition in United's squad this season, Mourinho will not be able to keep picking him based solely on last season's achievements.
An unnamed source from within the club told the Sun: “Standards have been raised under Jose and he wants his players to be focused on United.
“Martial is going through a tough time off the pitch, but it’s down to him to sort it out. The manager’s made him well aware of that.”
It has been a frustrating few months for Martial, who barely featured in France's run to the final of Euro 2016.
Memphis Depay, Marcus Rashford and even Ashley Young could all replace him in the starting XI if he doesn't get his act together over the next few weeks.
The Red Devils face also unbeaten Hull City, who are currently managed by one of Sir Alex Ferguson's old assistants, Mike Phelan, on Saturday.
Martial will need to have a good game - providing he is selected - at the KC Stadium as Mourinho will not want to have any bystanders in the team when they take on Manchester City after the international break.
Pep Guardiola's side have also started the campaign strongly but the clash at Old Trafford on September 10 will provide a much clearer indication where each team are at.
