The question is what does "true to ourselves" really mean? If it's a particular style of playing, then we should be prepared to suffer not winning anything for a while, if that style is just pleasing to watch, but doesn't produce results.
I would rather we play winning football, whatever "winning football" happens to be at any given time. If it's coupled with a beautiful playing style, great. If not, but it produces league titles and CL trophies, I'm fine with that too. Atletico aside, however, winning football will invariably also include football that is pleasing to the eye. And if it doesn't, a league title or CL trophy will more than make up for it.
Whichever way you slice it, the football that you play should be one that wins games. Beautiful football with no results will eventually get tiring too.
