Theoretically, games with West Ham should not be a problem for Bayer at all, since West Ham are only 7th in the Premier League and they even have a negative goal difference. But it would be great to see Bayer in the optimal lineup + it would be great if Bayer was 100% ready for a potential game with Liverpool. In the Bundesliga, games don't really matter anymore, there are just various statistical points of interest, like how long Bayer's streak of games without defeat can be and whether they can go through the entire season without defeat.
They should take every match serious and not look down on any of their opponents in every competition they’re participating in. Bayern Leverkusen should not settle for less but should try their best to win the trophies in the remaining of the two competitions they’re participating in. While the Bundesliga looks like they’ve won it, they should focus on the Europa League match against West Ham as it will be a shame for them to be removed by them. There’s more hope in the Bundesliga trophy than the Europa League trophy, so they should focus on it in order to prevail in the matches there as they’ve been doing in the Bundesliga matches too.
