I don't really agree. I mean, this is exactly what Ten Hag tried to do. He tried to play a mixture of tactics to suit player strengths and it resulted in disjointed nonsense. He tried to build out from the back, press from the front, get into counter attacking situations, and also try to play quick transitions and he ended up doing none of this well.
Pep, on the other hand, got rid of Joe Hart on day 1 because he didn't fit the system. He almost axed Walker because he wanted his fullback to tuck in more. He's consistently prioritized players that have great technique, tactical flexibility, and those who fit the system he has from the ground up and you can see the rewards.
