Conference league is always meant for the minor teams I really don't know what a big team like Chelsea is doing there Chelsea are meant to play in the Europa league where they can match their equal or mate just imagine Chelsea academy winning a team 8-0 scoring 6 goals in the first without much stress.
What are you saying mate? There is a requirement that qualify a team to play any of the league you see them. Teams don't decide which league to play and which not play, their performance determines where they will play in the following season. There are rules and the rules don't care how big you think a club is. They can only play in a league they qualify for. Even if Madrid, Barcelona or Manchester City failed to qualify for champions league or Europa, they'll definitely going to play in the conference league.
If it will be possible they should give Chelsea the tittle because they will definitely win it because they have 100% chance of lifting the conference league trophy because there will a stage in that league that they Chelsea team will start using their first team to play that game.
Just as you have said conferences league matches is never an interesting game to watch unless maybe the team you fan is playing and you nothing doing at the moment then you can decide to watch it won't still not be interesting because it is academy team that will play the game.
How sure are you Chelsea will win? Don't get deceived by that yesterday result because there is nothing like underrated team in football again. One of those so called small teams beat Chelsea during the qualification round but Chelsea were lucky and escaped with the help of aggregate goals. I saw teams like Real Betis, Gent and also Fiorentina. Some of them have played champions league before and we can not just assume Chelsea will easily get passed of them to win the league.
