Regarding Leverkusen, I think the performance Xabi Alonso had in this team was really good and now Leverkusen is in first place in the Bundesliga table while didn't spend too much money like Bayern Munich did this season with Tuchel and there is still a two-point gap between them and Leverkusen.
Also, the next game for Leverkusen in the Bundesliga is not hard because Union Berlin didn't start the season well and they had a disappointing performance so far.
Bayern Leverkusen is one of Bundesliga teams after Bayern Munich keep unbeaten until playing 10 matches and managed top standings behind 2 points gap from second placed. Its looks amazing with Xavi Alonso success return Leverkusen to top performed although he hasn't spent much money for latest window transfer opening. Right now Bundesliga is not only Bayern Munich but also have Bayern Leverkusen and waiting until how many matches later consistency performance from Leverkusen, will give huge pressure until end season for leading top position or they will loss compete second half season above.
I am excited if Leverkusen can destroy Bundesliga as farmer league label with Bayern Munich only become the winner, most fantastic achievement in the end of this season Leverkusen become the champion of Bundesliga.
