It's not even worth my time or your time to talk about Manchester City in the Champions League Group G. They are going to win this group and the price is insanely too high, so let's move on.
I think most people are expecting this group to be pretty straightforward, but I do believe that Red Star Belgrade can play spoiler and potentially send RB Leipzig to the Europa League.
RB Leipzig lost Christopher Nkuku and Dominik Szoboszlai in their attack, but retooled with Lois Openda, Xavi Simons and Benjamin Sesko, so there isn't going to be much of a drop off. The biggest loss for RB Leipzig was Josko Gvardiol. He's a world class defender and the centerpiece around RB Leipzig's build up play. They signed Castello Lukeba from Lyon who is a prom ising talent, but the Leipzig defense will take a step back from allowing 0.86 npxG last season under Marco Rose.
Leipzig are also dealing with some injuries. Willi Orban, who is their rock in the middle of the defense now that Gvardiol is gone, is out until the end of November.
The depth in their attack is little questionable as well with Christoph Baumgartner and Dani Olmo likely missing out on the Young Boys match and potentially the Manchester City match on October 4th.
