I have been saying this ever since Pep came to City. He hasn't had consecutive matches where he had the same starting XI all season.
I remember I was extremely frustrated 2 years ago when he started Laporte as a LB and KDB as a RW and had Sterling benched because he wasn't fit in the 1st leg of UCL against Liverpool. It choked the team to play on the right and caused us not to get out of our half insinuating the Liverpool press that led up to the 3 goals in the 1st half.
It's not all Peps fault because I believe half of it is due to injuries. I mean he can only start who he has fit but we also didn't buy players in key areas so he doesnt have to shuffle players out of position. I think if he cools down on tinkering with the lineups and tactics we would be more stable. It's crazy how a 2 injuries in Sane, Laporte and Mendy's fall from grace has affected our team, not to mention Kompany as the glue to the defense
