Xabi has the freshness on his side that gives him a better perspective into the world of football, he was a player way more recently than Tuchel has ever been and Xabi played in bigger situations so learned more high level stuff there as well. Tuchel has the wisdom and experience on his side, he has managed a lot bigger clubs and have seen a lot more success on his managerial situations as well.
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.
