Neither manager refused to instil a focus on quality on the ball, possession retention, strong midfield play etc until one year after their appointment, which is the point. Ole is the only supposedly quality manager who is so maleable and adaptable, that his team doesn't have strong identity and it's looked ad a positive and something he's only deferring out of necessity rather than actually being unable to get it done.
Also, Pep isn't always the same. His Barcelona team was proper tiki taka. His City one focus much more on fast attacks down the wing and overloads out wide. Liverpool started with gegenpressing and now are mostly a possession based team. However both managers have put in strong basics in their team when it comes to retaining the ball, movement, intensity, cohesion, possession etc. and from thereon tweaks are simpler. It's different to not having a plan or not having strong basics at all.
