In the pair Frankfurt - Bavaria, in my opinion, Frankfurt is in great danger 
as Bayern will try to prove that this pair does not play the winner of the Euro Cup with the loser of the Euro Cup, but the current champion with an ordinary club.
Bayern first games generally end by a big victory but that doesn't mean that they sometimes miss it up. They will have Mane in the attack line, probably replacing Lewandowski. For Frankfurt, they will try to grab Mario Gotze among the other transfers. This game particularly might be challenging so let's wait until we get a better view on both teams days before the match. as Bayern will try to prove that this pair does not play the winner of the Euro Cup with the loser of the Euro Cup, but the current champion with an ordinary club.It's still unclear whether Sadio Mane will replace Lewandowski but one or two Bayern players if they don't have a big impact because the Bayern team is already very solid on all fronts.
while Frankfurt have had a fantastic 2021 season, I hope they will continue to develop to become fierce competitors in the Bundesliga so that this germany league is more competitive and fierce.
