Agree.
I mean I don't think Martial may have faced some problems with adapting to Mourinho's methods which is the case for a lot of footballers who have to tune into a new system. But I wholeheartedly disageee that we are seeing fundamental or even substantially shift in the methods applied by the player today. If anything, the change I see in Martial's game is mostly to do with the confidence that comes with the importance and relevance that he deserves to have in the team, and has not received from the current manager. Yes or course he picked up the ball and dribbled more in the past and his off the ball movement can improve. But A) have we made the use of a huge strength or his that he displayed in his first year and few footballers have? B) Are we now seeing a player transformed by Mourinho?. The answer to both questions is No for me. But it won't stop Mourinho and his supporters from beating his drum and busting Martial's to claim credit.
If anything, to me it appears as though Mourinho is holding the player back. He's a much better player today had LVG be coaching him the last two years (although it would obviously be miserable for us). I hope Mourinho ions out his deficiencies as most 22 year olds have them. But he needs to stop making the mistake of not celebrating /making the most of his strengths.
