Pep is similar.
At Barcelona he fell out with Thierry Henry who would not follow instructions to 'play with chalk on his boots' i.e stay pinned to the left touchline to create space for Messi.
At City he would only select Grealish if he played a more limited role on the left hand side where he was asked to draw defenders and play simple passes.
It's about the individual sacrificing themselves for the team and meaning they have to accept not playing on occasions when tactics demand.
I think Glasner is in a similar mould.
If he praises an individual it's usually in the context of a team performance i.e the collective effort.
If JRS, Esse and possibly Uche cannot for whatever reason fit what's required they are not selected.
It's nothing new.
I recall similar debates around England with the likes of Currie, Hudson, Osgood, Le Tissier and Hoddle and why mavericks such as these weren't being selected even if the fans loved their skills.
