The Leverkusen team is still strong enough to defeat any opponent this season, in my opinion, Xabi Alonso has signed about four players during the transfer window, so I don't see anything wrong with them, but we shouldn't expect them to play as well as they did last year, as they won the Bundesliga title without losing any game, they have only played two games this season, winning one and lose one, It would be wrong to assume that they won't win the league, I think Xabi Alonso has everything under control and they will return to their winning ways.
Leverkusen's position is just another surprising thing i don't even know what to say because the defending champions are in the 8th position and they might not be able to win the Bundesliga title this season because even if the season is just starting this is even a period were they have to tighten up their belt so that they can be able to win. and the players that Alonso signed this season are not doing him any good to me because if they are being productive they should not be hanging in the 8th position, the assumption is done by the kind of performance they are putting up and they are not putting up a good show and that is one of the main reasons i feel this season is not their season at all because 8th might be a number but not a good number to me at least for a start.
Furthermore, Leverkusen will face tough rivals this season, since they will compete in the Champions League, where they need to win every game. I won't be surprised or embarrassed if Leverkusen's performance did not go further this season, they had already achieved a lot this season, and it is not easy to win a treble, but I had strong confidence that Leverkusen was not done yet, and we would see more from them this season.
Leverkusen the game has not become more serious they will not be able to continue other rivals that will come their way, and competing in the Champions League is not even in their capacity because the Champions League is much more different from the Bundesliga since Bundesliga is a domestic league champions league is comprised of other clubs from other leagues and even Leverkusen played against arsenal I thought the game was going to be tough but it was a flawless defeat. I think you should watch more of their game because have not seen Leverkusen archiving anything serious this season, but since everything is still fresh, so they can be able make their dream come through this season.
