In an exclusive interview with Football FanCast, Rob Lee, who made 280 Premier League appearances, believes Anthony Martial has a problem with himself if he can't get motivated to play for Manchester United.

It has been reported by EuroSport that Man United are ready to sell Martial, who reportedly earns £250,000-a-week, as they eye up a squad reshuffle ready to challenge Manchester City next season.

Since he arrived as the most expensive teenager in history, Martial has featured 258 times for Manchester United, scoring 78 goals and registering 49 assists in that time, however Lee believes Martial may have an attitude problem as he never seems bothered when playing.

Speaking on Martial's future at Man United and why the Red Devils should look to cash in on the 25-year old, Lee told FFC exclusively:

"Martial has just been an enigma. He's got all the talent in the world but he just looks like he can't be bothered.

"If he can't be bothered playing for Man United, then I think you've got something wrong with you."

It's been a difficult season for Martial who has found himself playing all across the front line with very limited success in each position.

The French international has found the net just seven times in 36 games and has only scored four goals in the Premier League this campaign.
