Currently team having by Graham Potter with Brighton Albion I don't sure he can success with Chelsea without any experienced yet with big top team and not get trophy in his career. What have been worry is coming true right now with Chelsea can't win in last five matches and have beaten last three matches in a row at Primer League. I think Chelsea management have give huge pressure for Graham Potter if want long term existing at Chelsea actually Champion League trophy become realistic chance.
Its looks domestic league bit difficult reach to top standing after remaining many points with Arsenal, but Chelsea still have opportunity to win Champion League and learned more what the best achievement from current Chelsea manager Tuchel success in the first season with Chelsea become the winner in Champion League.
Indeed, Chelsea performed well in the UCL. They have a chance to win like Tuchel. But with the current conditions I doubt it. I don't think current players can compete with Man City, Munich or other big clubs. In 1/16 they will play Dortmund. I don't underestimate Chelsea, but Dortmund can always surprise. Chelsea must be vigilant. Even though that game is still a long way off, there is a chance Chelsea make a big transfer maybe that could change the chances of getting to the Final.
I think it is clear that we are not going to end up with too many big things, we are going to end up with a bit of a problem if Chelsea faces a big name club. The only possible way for them to go on is if they face easier opponents until a point, but even that will not be that easy to handle, most likely outcome will be them going back home.
Winning UCL multiple times in short span of time is not something many clubs can do, usually clubs don't win UCL that easily, so they won it just 2 years ago, and they do not have to win it again this year, sure they will want to, but they can fail and that's fine. They should focus on being in top 4 at premier league.
