Are managers right for sticking to their “philosophy”?

You hear “philosophy” thrown around a lot these days. But are certain managers right to stick to it even if it means lack of results? For me Pep is the only one who can justify sticking to it because it’s actually yielded nonstop results. Other managers tweak depending on the game and for me that’s what managers are meant to do and what they used to do. Fergie’s style of football was to win and it’s the same with Ancelotti, it’s hard to see a definitive style with those two, they play to win and altered their style of play over the years. As much as people think Klopps football was “heavy metal” he altered it a lot after a couple of seasons at Liverpool and it became more refined. I feel like a lot of new managers try to mimic pep with the whole philosophy thing. Yeah it’s great to have one but the most important thing is results. Look at Ange for example, for me he’s not justified in being stubborn to stick to it. There’s no shame in tightening your defence if needs be. With the attacking quality they have, they’d still be able to score goals. Attacking wise they’re brilliant but he won’t be a successful coach if your style costs you defensively. Amorim will probably get a pass because it’s not his squad and he’s probably testing out which players he wants to stick around next season and who fits his style of play. We’re seeing teams get relegated because they think they need to stick to their build from the back, possession based tactics. But for me if you don’t show versatility, you’re going to struggle to get a top job or if you do land one, you’re going to get found out really quickly and it’s going to end badly for you, like we’ve seen.
