I honestly don't remember from all leagues, but I know that United will be in it right? If that's the case, we need to consider United to be a strong contender for it no matter what you think of them. I know many people think that they are not that great, and mostly you are right, but we should consider how United is always United and they may end up winning the whole thing if they play it right, which is why I may put some small amount for them.
Well, they could be one of the strong candidates for the championship but the problem is that the Europa League is not as simple as expected.
Europa League champions are sometimes always unexpected even in the last 3 seasons where Franfurt, Sevilla and this season Atalanta became an underdog club that did not think they would become champions in this competition.
Even though if we look further there are several big clubs that are always favorites to win even for this season there are Liverpool and Leverkusen who are unbeaten, they must recognize Atalanta as champions in the Europa League.
This situation could happen again this season although for the group phase everything might go according to plan for the big club favorites but for the round of 16 to the final sometimes the situation becomes more difficult than imagined.
