Yes. I have come to think the same. Pep does not want any player that disagrees with him. But maybe you need a few in the mental mix of the team just like you need a balance of different profile players.
You absolutely do need players with personality and warrior mentality in CL, because it is very unlikely you will be a level above the competition, so you have to know how to suffer and come out on top. In the league no, you lose a game, no biggie, you win the next 10 in a row or something.
City were just minutes away from going out vs Atletico IMO for the same reason. They barely managed to hold on. Atletico with the pressure of the fans were all over them in the 2nd half.
They also have a problem with Laporte and Dias. You get the feeling that they are basically the same profile. Both technical but error-prone and soft. As in having two Piques and no Puyol and Mascherano top dog.
I'd keep Dias, sell Laporte, hopefully not to us.
