Leipzig should simply focus on the Bundesliga then the Champions League because, while they are doing well in the league and pursuing Bayern Munich in the league standings, they are not doing well in the UCL, and I am sure it will be difficult for them to go to the next round. Bayern Munich's next match is very easy and I am sure that will be a pure three point for them this weekend, but Leipzig's match will be so hard for them to achieve three points because Monchengladbach are good and they strongly against Frankfurt that are doing well in the league this season, so they will do anything possible to achieve three points so that they can move forward in the league table.
Leipzig will be the favorite to win the game, because they have lost their last game in the league against Dortmund and lost in the UCl. I am sure they will do well and get three points at home. Let see how the game will end this weekend, many clubs have improved and are doing well in the season, that is how I like competition to be, they should be competitive in the league, not like PSG, who usually dominate the League One, every season and win the title. And they are not dominating well in the Champions League competition just win one match at of four.
