#5 There’d be less pressure on him elsewhere

Despite their downturn in fortunes since the departure of the legendary Sir Alex Ferguson in the summer of 2013, Manchester United remain undoubtedly the biggest club in England. It might be painful for fans of sides like Chelsea and Tottenham to admit, but the global power of United is pretty much untouchable, and their fanbase is as big as any other club on the planet. But that isn’t always a good thing for their players and manager.
Since the departure of Ferguson we’ve seen three bosses struggle to live up to expectation, and players who looked great at other clubs – the likes of Henrikh Mkhitaryan, Morgan Schneiderlin, Juan Mata and even Paul Pogba in his early United days – have struggled under the weight of the United shirt. And while Martial seemed to take to it like a duck to water at first, as his form has worn off slightly he’s seemingly found the pressure of being a United player harder.
A move to another club would ease that pressure massively – even if it were to another Premier League title contender like Arsenal or Tottenham, or a foreign side challenging for a title like Atletico Madrid or Bayern Munich. The pressure at United is really only comparable to that at Real Madrid and Barcelona, and for a young player, it can be stifling. If he wants to develop his game while not being under such an intense microscope, then perhaps it’d be a good idea for Martial to move on.
