3. A sense of unpredictability
Bayer Leverkusen's dominance comes down to a lot of things and it would be unfair to say that Bayern Munich have performed badly during Leverkusen's greatness. However, what separates the two sides is that Xabi Alonso has Tuchel's number, but Tuchel doesn't have Alonso's.
This is because it's been proven this season that Xabi Alonso is a tough nut to crack and I don't mean this by the literal definition. Granted, Leverkusen have a great defensive record, but I mean that it's difficult to crack Alonso's tactical code.
Every game, Alonso sets up in a new manner which will best matchup to the strengths and weaknesses of his opposition. This is a rare trait to find in a manager nowadays but it's a trait which not only has Bayer Leverkusen at the top of the Bundesliga table, but Alonso on the radar of top clubs.
If there was ever a manager who personified being unpredictable, it's Jose Mourinho. Not only are his actions on the touchline unpredictable, but the way he sets up is second to none. There's a reason why he's competed with some of the greatest footballing minds such as Sir Alex Ferguson and Arsene Wenger and that's because he played the occasion, not stuck to some boring outdated principle.
To cut a long story short, Bayern Munich would be a different breed and a force to be reckoned with under Jose Mourinho.
