So, when you combine those two together, you do get a great manager, but when they are facing each other, I believe both have their advantages and disadvantages. I believe that we are not going to end up with anything that would get better, it should not be all that confusing, it should be quite the normal situation and do better in time.
I saw Xabi still playing football when Tuchel was coach. So in terms of experience, Tuchel has a lot of experience. But here we see, old statistics cannot always show the strength and intelligence of a coach at one time. Xabi is a new coach but he is quite a genius with Leverkusen at the moment. Xabi was able to process well, not making many big transfers.
This is different from Tuchel, even though the financial conditions are very different. Tuchel was given the facilities the players needed to meet their championship targets. He is also a good coach, he made Bayern play better when Kane joined. Currently Leverkusen and Bayern Munich are competing fiercely to win the Bundesliga.
