Carlo Ancelotti may preach a different type of football to his predecessor Josep Guardiola but Bayern München have continued to dominate when allowed to cut loose.
The results have kept on coming, but the differences between Josep Guardiola's Bayern München and Carlo Ancelotti's version have been clear for a while. It has felt like intense domination has given way to a more passive level of control.
However, in the UEFA Champions League any gulf between the two coaches' regimes has not been quite so clear. Wednesday's 5-1 round of 16 first-leg demolition of Arsenal was Bayern's 16th straight home win in the competition, spanning the eras of both coaches. Whoever is in charge, it's the same old Bayern in Europe. Off the leash, they're fearsome and few teams can stop them.
One of the first things Zinédine Zidane did when becoming Madrid manager was to bring Casemiro into the centre of midfield in his 4-3-3 set-up. Since then the No14 has played every game when fit, and it is not hard to see why. Mobile, indefatigable and strong, he has all the tools required of a modern-day midfielder.
Casemiro's raison d'être is to win the ball back, get it under control and recycle possession quickly and concisely. He knows he is not there to play Hollywood balls or get the goals to fuel victory. He is a player that does not over complicate things and will never shy away from a tackle – the kind every coach loves to have.
He might not be the most talented member of this Madrid outfit, yet through sheer hard work and determination Casemiro is carving himself into a cult figure among the Bernabéu faithful. Moreover, he has made himself undroppable in Zidane's current line-up.
He allows Modrić and Kroos to do their thing This Madrid midfield is wonderful when firing on all cylinders, with Luka Modrić and Toni Kroos pulling the strings and using their vision and range of passing to push the team forward. However, Madrid's dynamic duo would not be able to function as they do without the former São Paulo prospect behind them.
