Bayer Leverkusen is one of the clubs that opponents fear in the Bundesliga. Not all clubs can beat Laverkusen easily because they were at the top of the standings last year with good performance. It would be really good, as you said, that Laverkusen should add several senior players and star players, especially strikers and defensive midfielders, so that they can be more confident of winning this season.
I don’t see anything wrong with this squad and they can still fo wondrous things also this season. Adding more senior players to the team will really help them but I don’t think it’s a necessity now that the league have started and they started on a good course. Bayern Leverkusen still remains one of the strong contender for the Bundesliga title this season and without putting that great performance together, they will not be able to keep that consistency of wining the league again. Many clubs should fear them but i don’t think they’ll get it easier as they did last season. The league just started but they can’t keep the unbeaten streak this season after losing their most recent match, that shows how tough this season is going to be for them.
This season, of course the competition is getting tougher and Bayer Leverkusen is impossible to show the same results as the record in the previous season, the teams that previously experienced a setback would definitely make improvements to the squad to be better and become a heavy competitor again, so this is very Naturally, especially this is a season that is still early for us to watch.
In another perspective, we don't know what Xabi Alonso planned with Bayer Leverkusen, whether he was testing a new strategy or what, because the previous season must have been predictable to be easily defeated, adding senior players or stars might be done But I think they are not ready with salaries that must be given with a large risk, because not necessarily also adding new experienced players will make them much better if they are not accompanied by the strategy needs made by the coach.
