This season 24 of my friends played in CL/SL final (2 of them played together so it is 25).
It is a good percentage.
23 of them won.
Even better percentage.

One of them lost, after a fixed game (classic - GK motm)

From a point of view, you can say ok, 1 out of 24 games went wrong.
But it's a pity for this guy who spent a lot of time and sources, not to win the title (and the treble).
