Martial did nothing... Tracking back is part of his job. Shouldn't be commended, or seen as some favour.
He needs to learn how to really play this game, because he is far too ineffective for someone of his ability, and thinks he is better than what he currently is.
Talented yes, but he has to change his attitude if he wishes to be the player he could become.
Great young players inspire teams. Anthony Martial doesn't do this. Look at Sterling. Look at Rashford (who also really doesn't benefit from the side-show called our Manager).. he is an inspirational player.
Martial has many supporters on here, but some people need to see things as they are, not what they wish.
As someone mentioned, this isn't PlayStation.
