Regarding Italy it's not only a "deep fall". Italy's late history is an unique roller coaster ride. It looks like Italy has two faces: The beautiful Euro face and the ugly World Cup face.
All started in 2010 when Italy got humiliated in a WC group with New Zealand, Paraguay and Slovakia and finished on last place without a win. Against the odds Italy quickly rose like a phoenix (ESC reference not intended) and they reached the final of Euro 2012. I remember Balotelli has his one great game for the national team, when he knocked us out single-handedly, although we were on our peak back in 2012... Anyway, Italy went to Brazil 2014 with good confidence but yet again failed to get over the group stage, losing to Costa Rica. Then in 2016 I remember Italy had a lot of injuries prior to the Euro and they were considered a potential flop once again... and they did what? Beating the eternal dark horse Belgium and defending champion Spain. We beat them in quarter final but we needed an never-ending penalty shoot-out to do so, although we were still close to our peak level. Then Italy ended up in the play-offs for WC 2018, which wasn't exactly a shame because they were unlucky to get drawn with Spain in the Qualification group. Italy however failed to score a single time against the Swedish wall and missed the WC.... typically they got their shit together right before the Euros, deservedly won the tournament. Kept a clean sheet for 12 consecutive matches (until Austria scored against them), broke the world record of most unbeaten consecutive matches (36) but then gave away what looked like a safe WC qualification because they choked against Bulgaria and Northern Irelanad and Jorginho missed a late penalty against Switzerland which would have booked their tickets for Qatar...
I mostly support Italy because I have Italian origin on my father's side, yet I've never been a crazy fan. But if I was, I would have driven mad long ago. The only predictable of Italy's performance is the unpredictability. Well, actually if we get rid of World Cups and only play Euros, Italy shall do consistently well

But to think that in in 2025 people get full-aged who weren't even born when Italy played their last knock-out match in a WC (final of 2006) is utterly crazy. About the yesterday match I wonder how should I explain to people who didn't watch the match how Berardi failed to score from this position
