This is a very tricky game for Liverpool, few weeks ago i felt that Liverpool will comfortable get the win in this game, but atm, Liverpool's form has really depreciated and Leipzig is the kind of team that can cause an upset; the only good thing for Liverpool is that the second leg will be played in Anfield and at home Liverpool will definitely have the advantage, while the first leg will be played on a neutral ground, which prolly doesn't favor anyone.
Come on. No matter what anyone says, Liverpool is a top Premier League club. Although for me the Bundesliga is stronger than the Premier League. But they are different "Weight class" clubs and right now Liverpool look stronger. Although in football anything can happen and even a weaker club can win.
It depends in which categories to judge, because excluding Bayern I would not say that the other leaders of the Bundesliga are stronger than the Premier League.
