Mostly because the Rags beat them 5-0.Why the fuck do you think Leipzig is a pretty easy draw?
But if you really want the full reason:
Sevilla haven’t lost in over a month
Lazio lost once to Atalanta since mid-Jan
Barca is Barca
Atletico... LOL wish that could happen again, also top in La Liga
Can’t play Atalanta
Only Gladbach, Porto and Leipzig left. Porto is less favorable as a matchup given the low block that has given the Dippers problems. Whereas
Leipzig will give them opportunities to score
Leipzig>Gladbach.
Basically everyone else they couldve played is on-form and/or equally talented. Leipzig have shown a propensity to stumble, both in UCL as well as in Bundesliga.
