Although Alonso seems as a threat with the current performance and display from Bayern Leverkusen but Tuchel who's more experienced has drafted out his plans, processes and techniques and he seems ready for any competition that awaits him. He's got a good team for himself and I believe he'd be able to be victorious in 95% of his encounters. Bayern Munich is just one good team that are a general threat to every team they're up against and they have better victory chances too.
Honestly, I still think that Bayern has the most potential to win the Bundesliga trophy this season. there are many factors that become my reasons for the predictions or speculations that I make. and one of them, the points you have said. we agree, this giant Bundesliga team has a very good combination of players. in terms of team depth, Bayern Munich is stronger than any other team competing in the Bundesliga. even though Leverkusen still occupies the top position in the standings, that doesn't mean Munich can't shift them. it's only a matter of time for Bayern to become top of the Bundesliga standings again. apart from that, maybe Tuchel will bring in some new ammunition to strengthen his team and patch up its weaknesses. even though I haven't followed the developments, what is certain is that Tuchel will prepare his squad to appear more fierce in the match they will play. regarding the Champions League, I haven't heard that Tuchel is targeting that trophy. but what is certain is that the Bundesliga is Bayern Munich's main target.
Talking about Leverkusen, IMO, I actually suspect that Xabi Alonso's squad is under great pressure. I mean, they will try their best to maintain their performance to stay at the top of the standings. so psychologically, Leverkusen allegedly has a mental burden on their shoulders to keep performing well on the right track. on the other hand, Leverkusen will face Bayern at the BayArena in the next few weeks, only now Bayern Munich is different when the two teams met in the first match. one of Bayern's weaknesses at that time was the goalkeeper, namely Ulreich. also, several of their defenders were injured. the meeting between these two teams will present an interesting match. the point is, Leverkusen must win the match. or at least, end in a draw. thus, conditions will turn around for Bayern Munich who have the burden of shadowing Leverkusen. however, if Thomas Tuchel's squad is able to get full points, it means they are on their way back to the top of the standings. but however, everything I say is still based on assumptions. to find out more, yeah, let's enjoy the competition between these two teams.
