I also have a feeling that Leverkusen will struggle more when facing Liverpool at Anfield and Liverpool themselves are also very aware that Leverkusen are a little different from last season so Liverpool will try to beat Leverkusen when they visit Anfield in their next game next week. Also I see that Leverkusen's draw in the domestic league has really given Leverkusen a very different assessment for this season because Leverkusen drew with Werder Bremen who generally have not been so strong this season and Leverkusen even took the lead in that game.
Yes Leverkusen next match against Liverpool at Anfield will be tough. Liverpool knows Leverkusen has improved this season and will be ready. Leverkusen recent tie with Werder Bremen weaker team.is concerning. They could not win despite leading. This shows Leverkusen is vulnerable. Liverpool has home advantage making them more likely to win. Leverkusen struggles against weaker teams do not give them much hope against a strong team like Liverpool.
The last 2 matches against Brest and Wender Bremen can be a reference that Leverkusen's performance is not as strong as last season, this club was only able to get a draw, so in the next match Liverpool can take advantage of that weakness to beat Leverkusen but the possibility of a draw can still happen, usually Leverkusen always tries not to lose and when they have difficulties they try hard to equalize, in this match I am also very curious about Xabi Alonso's strategy when facing his former club and of course the match between these two clubs will be very fierce.
