Cech insists there's still plenty of tests to come.
"We're in a good position, but we have a long way to go," said the shot-stopper. "We have to go to Anfield, play Arsenal, still play difficult games, so we have to keep our feet on the ground and keep working towards our target, game by game, and see where we go from there.
"The table can change quickly; we saw that over the last few months, the table has changed many times. Arsenal suddenly disappeared from the top. I think, and still believe, City is the main rival and favourite to win, with all the players they've got, and the quality and experience they have. I think it'll be tight until the end."
