Because Carlo doesn't believe in a single system and has said so himself. He is pragmatic, he takes it game by game, the players he has currently fit aren't good enough for nice football, we played some really good stuff at the start of the season because we had a fully fit squad of good players, we now have Iwobi trying to play football, Gomes jogging around the pitch, Holgate being dog turd with his passing, Gylfi not getting involved enough, Allan coming back from a long lay off, Davies coming back from injury. We need to grind results out right now, if it isn't pretty so be it just get points on the board
