I think that is a pinpointed difference about both managers, Tuchel believes and trusts in his top players and disregarding the youth talents in the team while potter embraces them and is willing to give everyone a chance because who knows how instrumental they could be in the team, I guess that should be the real reason Tuchel was sacked in the first place because I have heard different sides to the story and most people are saying the same thing about Tuchel's poor communication skills and poor tactics.
It's a tricky question because Tuchel became a sophisticated manager and maybe he really paid attention to the top players, even though he used to start out as a Potter and trust young players who were full of desire. It's a question of opportunity, Tuchel has become a top coach and his opportunities have changed, in such conditions the mindset also changes.
