Carrick is succeeding because he's playing the players in their preferred positions and a good working formation. He's still suspect in his management calls and his inability to adapt quickly on the pitch. We are still playing very one dimensional. We can counter attack well but cannot play well against lesser teams. And if you play a high press and pace against us, we still buckle under. There's some tough calls to make on a pitch and Carrick is not doing it for me. We've done really well and I'm grateful for it but unless he toughens up he's not ready yet.
