Chelsea's current performance is commendable this season and if they can maintain it without losing form in the middle of the premier League season, they could be a team to be feared this season. There's a big improvement in Chelsea's attack this season, and I think Chelsea's attack would be a problem for their opponents this season. Since Abramovich sold Chelsea to Todd Boely, this is the season Chelsea is have a complete team, so I believe Chelsea would beat some of the big clubs you mentioned.
Chelsea have strengthened their squad this season. They have added some talented players to the squad. And we are seeing some decent performances from Chelsea. Even though they could not win the first match, we have seen Chelsea players perform well in the next two matches. The team won against Fulham and West Ham by dominating. But I am waiting to see how the team performs against the big teams. Chelsea is going to face the giant Bayern Munich in the first match of the Champions League. I am waiting for this voltage match.
