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.
Chelsea has just changed their coach,I think we should give him some time before results will start to come.If these results do not start coming despite the new tactics that this coach will implement then there is only one possibility left for Chelsea to not lose a lot during this season and that time is the January window transfer,they should be very active and start since December if things do not go well during October (November is World Cup) and buy some good attackers where it looks like they are suffering the most.
