Bayer Leverkusen matches the same strength with Bayern Munich. You're right, consistency is the only key that will make mediocre club transforming into becoming an elite club. Bayer Leverkusen ranked first this season, they really got some guts to maintain the lead for some weeks. They have one of the best coaches, Xabi Alonso who's not relenting, making sure he knots every area on the pitch. With the present game performance, it will be difficult for any mediocre team to win them, they already know what to expect and they're ready. Xabi Alonso at their peak moment in the present season games.
IMO, Leverken does not have the same strength as Bayern Munich. after all, Bayern is one level above Leverkusen. What made Leverken become what it is today, was the presence of Xabi Alonso as coach. However, it cannot be denied that several Leverkusen players also have quite good talent. Plus, the system that Alonso has implemented for his squad is working as it should. This team does not only rely on one striker who is the goal scorer in their squad. However, several other players are also quite productive in terms of scoring goals. Apart from that, they created a solid game. and as a result, Leverkusen is now at the top of the standings. even though in fact, they have the same points as Bayern Munich. We'll see how consistently Xabi Alonso will bring his team into competition in this competition. The reason is, the Bundeliga still has a lot of matches left in the future. which means, we cannot be sure what will happen in the next weeks offered by the Bundesliga.
On the Bayern side, I haven't seen their best performance yet. Kane, can become even sharper as a goal scorer as the bond between the players and coach becomes stronger. Apart from that, Tuchel will also not allow his team to be below Leverkusen's ranking. We'll see, because the competition in the future will be even more exciting.
