Bayer Leverkusen have not shown that they will be champion this season. It might be too early to judge them but they have struggled to get wins from low-placed teams. They were not impressive against Borussia Monchengladbach and also struggled to beat fourth-division FC Carl Zeiss Jena in the first round of the DFB-Pokal. Coach Xabi Alonso would have to find means to make his team create and also maximize opportunities. The game with Champions League side RB Leipzig will be a good test to show how the team is improving. Leipzig also has three points in the Bundesliga after edging over VfL Bochum scoring one goal and conceding none. Leverkusen will be without captain Lukas Hradecky but hopefully will do a good job.
Bayer Leverkusen is showing seriousness and they still have a very strong interest in winning the Bundesliga again if they play hard and acquire the required points then I don't see anyone stopping them but if they don't meet the requirements then there will be a serious problem because there are teams that have the same target so if Bayer Leverkusen can not defeat them to meet their target then because it is now like Bayern Munich is also targeting that same trophy and Dortmund and everything is no looking as if they want their glory back that is for Bayern Munich and Dortmund that have lost their place in the Bundesliga and that is one of the reasons they are given kompany a lot of pressure and for now the performance is still in place so its hard to decide what exactly will happen. Bayer Leverkusen's game against Borussia Monchengladbach was not impressive for me because the guys had the chance to have a draw game, Bayer Leverkuse's last five games are not an impressive one for me, and their game against RB Leipzig will be waiting to see what Bayer Leverkusen will play today.
I think it would be unfair to expect Bayer Leverkusen to repeat the performance they showed last season. Even teams with very large budgets and star players cannot achieve great success one after another. A very good and successful season has passed for Bayer Leverkusen and they will try to do their best this season. As a fan, I do not expect them to be as successful as last year. Finishing the league in the upper ranks and reaching a certain level in the European cups will make them successful this season.
Bayer Leverkusen has a good understanding of the game and they are trying to show it on the field. They won many matches in the last minutes last season and this made them champions. It may not be right to expect the same success from them this season. They are trying to play good football and we can see it on the field. For now, I do not have great expectations from Bayer Leverkusen, maybe this will change in the middle of the season.
