Pep did, and so did the entire league when Klopps Dortmund turned into a relegation struggler for months, cause the enire league figured out how to play against him and Klopp couldn't find an answer to it, and eventually ended up finishing 7th (47:42 goal difference, 46 points) With what clearly was the 2nd best team in the league.
You don't play against Klopp sides. You let them play, just like Pep did once or twice. He Set up with a back 5 (343/523) and gave them the ball, watching Jürgen scratch his head and continue the same approach for 90 minutes, cause he can't adapt to save his life. It's just that Pep seems to be too proud to give possession to the other team, otherwise i see no reason why he wouldn't make use of that successful tactic again.
