Chelsea still needs more improvement to match PSG, the performance during semi final can't give them trophy favorite, after scoring first goal they became relaxed and jokey. Another issue will be from the coach when he fails to start his first team or decides to set players off position. In as much Chelsea don't stand a chance, i expect them to give a brief outstanding performance during the final at least as opportuned to qualify for the final, i don't want a similar result as PSG vs Inter in the Champions League final.
The problem I have with most of us is that we analyze football with sentiment and it is too bad, PSG team are humans who will be facing with other humans too to dig it out, so let's not conclude things , let's wait till that day, I will tell you for free that Chelsea will never joke with that final even though PSG win them it won't be with much goals but I still doubt I that will even happen in the first place, with what you've said I don't think you have watch Chelsea in final matches, if you have, you will know that there effort have never been a joke, although you'll say is not with the particular current team but what I want you to lmow is that it can never be like PSG and inter UEFA champions league finals.
What is certain is that Chelsea performance will not be as bad as Real Madrid against PSG, so there is no harm in pinning hopes on Chelsea. It's just that when PSG is favored it is also a very natural and reasonable thing if you look at the PSG trend which continues to humiliate the big team. I will be happy if there is indeed a team that can overthrow PSG because until now no one has been able to do it.
