Chelsea Vs Manchester City would be one of the most interesting games in the season so far, two teams that only love to attack, I do not think anyone of them would pay too much attention to parking the bus, city are more mature than this current Chelsea team and I see that being the edge for them, city win 3.1.
I think in this match City will settle for a draw or even they may lose the match. City is under pressure. The fame, the expectation and finally the attacks from Chelsea will give them hard time. And Chelsea knows if they can win this match then they will go one step ahead than the closest competitor.
I agree that the game will be difficult for Manchester City, but I don't think the chance of Chelsea to win the game is much higher than Manchester City.
Manchester City will play at their home and it's a great advantage. Except the game against Wolverhampton, Manchester City hasn't lost any game at their home in this season of premier league.
I think you are predicting the result based on Liverpool vs Manchester City game. That game was totally different. No team can defeat Liverpool.
