That's right friend. Now Leverkusen just need to maintain their performance so that it remains consistent at the current level. Because if Leverkusen can maintain its best performance until next season, it will give Leverkusen the potential to go further, even in big competitions like the UCL. But what I'm worried about is that the great players Leverkusen has might receive offers from other clubs. And it's possible that some will leave in the transfer market later. And that will definitely have an impact on the strength of this team next season.
For the great players they currently have, many other big teams are already targeting them, but so far I haven't heard any news that the players will leave, we'll see until the transfer market comes.
They have to prove themselves in bigger competitions, such as the Champions League next season. If they can maintain their consistent play like this season, I'm sure they will be able to perform well next season too. But it takes time to see it all.
