Chelsea are doing much better than before. They are playing very well now and I think they have a chance of winning the Premier League. Because before their position was comparatively bad but now they are playing well. It is never possible for everyone to play the same way. Sometimes they will play badly and sometimes they will play well. This is very normal. Last season Chelsea did very well. This season Chelsea is a little bit worse. Chelsea is not in good form at the moment but it will not take long to get back to form. Because Chelsea went to the Club World Cup and their condition was very bad. At that time Chelsea was winning.
Chelsea have been on good development and improvement track in two latest seasons and they have a likely best attacking midfielder, play maker in Premier League next 5 or 10 years, Cole Palmer. They were very lucky get him from Manchester City when he was not given chances he asked for and Chelsea got him while now Manchester City and Pep Guardiola have to struggle to replace Kevin De Bruyne.
It will be very interesting opposite future of Manchester City and Chelsea in the near future around only one single player Cole Palmer who is a start of Manchester City decline and beginning of Chelsea return to top of Premier League.
Liverpool's strength is indeed much better than several other teams, but the last three matches aren't enough to secure the title this season because there's still a long way to go until the end of the season. Chelsea have also shown significant changes this season and they shouldn't be underestimated. If they can perform consistently throughout the match, I'm quite certain they will trouble Liverpool. Chelsea are also unbeaten so far, with two wins and one draw, so Chelsea's chances of catching Liverpool are very real.
Liverpool were already so strong last season but they have been stronger after this summer transfers by buying many new and young star players for the future seasons. However their spendings on transfer market this summer and high salary contracts given to those star players will put their club finance at higher risk in coming years. Liverpool must maintain good performances and win titles in Premier League, go far in Champions League to prevent a financial crisis in coming seasons.
