I think Group A will be as tough as Group B. West Ham, Freiburg and Olympiacos are all good teams in my opinion and they all have a chance. I expect them to be very competitive matches
At least Liverpool popularity in the Europa League this season will be the favorite for get the title, but we also cannot ignore about Bayer Leverkusen in group H. After all, if I have to compare between West Ham and Bayer Leverkusen, then of course I will choose Bayer Leverkusen. Because at least, Bayer Leverkusen has become great from last season too. Moreover, Bayer Leverkusen are also in a group that can be said to guarantee for Bayer Leverkusen to qualify for the next phase, and it is also very possible for Bayer Leverkusen to become group H winner.
So yes, I personally prefer Liverpool and Bayer Leverkusen to be in the Europa League final this season. But yes, we also still don't know what kind of team will be thrown out from the Champion League and continue in the Europa League. Because in fact, last season Sevilla also played in the Champions League and then, because Sevilla only finishing in third place caused Sevilla to be knocked out and continue in the Europa League, until finally Sevilla won the title.
