Chelsea after change of management and coach surely in decline and have no enough chances, but Liverpool performance is surely a big shock for fans and team management, but many things can change in coming days who are going to win is surely not clear right until now.
Chelsea will not be fighting for the title this season. I don't even think Chelsea will qualify for the Champions League. Their biggest weakness is their attack. Chelsea players have scored only 8 goals in 7 matches. Manchester City scored 23 goals in 7 matches. Even Tottenham managed to score 18 goals in 7 matches. Chelsea's performance will not improve without the addition of talented players in the attack.
I'm not going to compare Chelsea to any other club, because it's very clear that their stability is poor now, both in terms of their squad and their form. They failed in the transfer market last summer, it was a disaster as we see it now. Even now I am skeptical of their match even though the opponent they are facing is a weak club.
The sacking of the coach they did did not provide a better solution. The loss of several key players who have been a mainstay in the squad for the last few seasons has a bad impact on their performance. And I also think, to be in the top 4 is very difficult for them.
