This is why Guardiola is maybe one of the greatest managers of our time. When they asked him if he might change his style of play, his response was simply

:
“Yeah, after 18 titles I will change my plan, after winning four Premier Leagues in a row I’m going to change the way I believe my football teams are going to play... NEVER, EVER WILL I CHANGE MY BELIEFS IN THE WAY WE ARE GOING TO PLAY!
But, if we regain up the pitch I want to attack quick, when the opponents high press man-to-man and we break the first press I want to attack quick, but after that I LOVE TO PASS THE BALL, A THOUSAND, MILLION BORING, BORING PASSES, I LOVE IT!”

I have to admit, I love this about him. I prefer attacking football way more than the tactical style of, for example, the Italians.
I don't see anything smart in his words. The fact is that everything changes and you need to adapt to new conditions. If you try to play according to one scheme regardless of anything, then this is called lack of feedback and is a sign of a broken system. And separately, I want to note that the adequacy of Pep's scheme has not been proven at all, since it does not work unless he literally has a golden dominant squad. I would like to see what success he would have achieved with, say, Brighton, Betis or Roma. Most likely, none.
