It’s the role of the manager to get them to perform, to implement the right formation and tactics, to give them the required mindset.
In that case Poch deserves massive credit and praise for getting us to the CL final in the first place.
Oh and in case you try your usual tactic of deflection, he also deserves massive praise and credit for getting us to a top 4 place with a squad that suffered many injuries to many players at the same time, some of them long term, and no new players for 2 transfer windows.
You can't have it both ways.
