Manchester City's form this season cannot be compared with Liverpool's poor form. Liverpool have some work to do to get them back to winning again. Manchester city are looking much more favorites to win the league again this season, Arsenal have showed they can be competitive but I doubt their squad is good enough to carry them till the end of the season.
What can we talk about if the bookmakers estimate the probability that City will become a champion as 1.34? At the same time, City is not even in first place in the standings at the moment. Even if this assessment is slightly wrong, City's superiority over all other teams is beyond doubt. Even a World Cup break is unlikely to throw City off course for the championship.
