If he would be able to, he would've been able to get to atleast one UCL final in the last 6 years managing the best teams in Europe. Yet, in almost all his years, he went out because he his team was too defensively vulnerable and we being caught on the counter (Real 2014, Atletico 2016, Monaco 2017, Liverpool 2018, Spurs 2019). That weakness of his has been exploited time and time again, we've seen Klopp change his system to avoid those problems which plagued him last season, which is why they have had a much better defensive record this season in the league and Europe but Pep doesn't seem to have that plan B. That was his problem at Bayern and has been for City in Europe.
