Maybe Chelsea might have luck on Manchester City, but it will be so surprising. Although Chelsea always finds it simple to win teams that are stronger than them, I don't think it will work for Manchester City.
Despite predictions of pundits and optimists, I believe the odds of Chelsea winning this game is very slim. Manchester City look menacing right now, they will not want to lose any game. There is hardly any side that can compete against City at their level, Pep and his boys are likely to give Chelsea a good thrashing today.
