Yes, luck is part of the game but luck alone does not explain the crazy recoveries of Real Madrid during the 80s in European competitions, the never-die attitude to overcome adverse results in a big deal of the games of the 2006/07 Liga or the comebacks vs PSG, Chelsea, City and Sevilla in less than two months in 2022, just to name a few examples that come to memory.
This is sustained on a seemingly simple principle: players and fans believe the result will be overcome because the myth exists and the myth exists because fans and players belief make it materially possible.
I don't buy this storytelling we're being fed this year about the "never die" attitude, the fans "believing the team will prevail eventually" and all that stuffs. When you take the games against PSG, Chelsea or City, the stadium was pretty much dead before the 1st goal was scored.
Real was able to take a great advantage from their momentums. That, i'll give it to them any day of the week, that was impressive. But before they scored, nobody was under the impression that either the players or the fans had the deep feeling they could do it, constantly pressing forward, giving their all to get the win. They looked toothless against PSG before Donnarumma screwed up, totally outplayed against Chelsea before they screwed up and the same happened against City when Grealish missed both chances (well one was an amazing save from Courtois who's hands down the best keeper in the world at the moment).
But boy when they scored that 1st goal, the push was impressive. Playing 3 second legs at home certainly helped though.
It's a new found storytelling the media found this season to sell paper but where was this spirit last season when Chelsea totally controlled both games? Or the year before when City dominated easily? Or the year before when they got obliterated at home by a Ajax team mostly made of younglings?
