You forgot to mention the maniac that is Diego Costa.
To be fair, the situation with Pedro and Fabregas was not as bad as the other. With Pedro, it was a classic case of a player taking time to settle into a new league etc while with Fabregas, it was a case of a player trying to prove the manager and force their way back in. With Torres, Kepa and Morata, things just got really shit for them and I some times wonder if the other players in the team and/or manager have tried to speak with them etc because like in Kepa's case, there seems to be no connection between him and the defenders and everything just falls apart in matches. Like do they talk about doing this, doing that, making sure A does this, B does that etc.
