Have a look at my post on the Jose poll thread - I talk about how Jose's tactics ends up covering players with one individual role (Lukaku solely playing as a target man, Matic focusing purely on defensive midfield duty, felliani getting either a clear defensive duty or an attacking duty during the game) - however it ends up singling out players who have to carry out multiple roles.
Martial is our attacker - but also had a significant defensive duty last season; for that he got targeted. Pogba is our main creative midfielder; our most attacking midfielder we have - yet his role is not to concentrate on that purely & is being targeted due to his lack of defensive aspect to his game.
Clearest point is with de bryune - under Pep he is given a clear attacking role in the team which is to be rinsed & repeated. What happened under Jose? De bryune never was the traditional CAM that Jose would want so pushed him out to the RM where he was given both an attacking & defensive role - rather than having a single gameplan to focus on.
The players that do well under Jose have a very solid, single role to fill. This covers players who are purely defensive, purely attacking, purely meant to keep width etc. Players that are made to do more than one, players made to do defensive work as well as attacking work, players thst are made to cut in and keep wide etc - tend to fail because none are carried to 100%.
