Not toxic, is just that with this kind of game mentality. I really doubt I will ever see a CL final winning.
Yeah there are exceptions like Chelsea of Di Matteo but thats it.
And in the other hand, yes its important to win of course that is beyond question but at the end this is a sport to entertainment at the end.
And more boring games than we have had is difficult to find. Not only boring but flagellant is the correct term.
