This is not the first time they have failed because in 2018 they did the same thing and failed to go to Russia at that time.
Actually there is nothing wrong with Italy but indeed they are a big team and with above average quality players which makes them overconfident and this is the second period they have failed and interestingly they failed towards the end. It's a shame but we can't do much because from an individual point of view they were good but from a team perspective they were lacking and they failed.
this is football, a lot of unexpected things happen, italy there is no regeneration of players and currently in their team there are a lot of old players, i think their failure is not surprising. In almost every World Paila event, the favorite team failed in qualifying.
despite their achievements that can win the EURO 2020 title but in terms of performance and also the composition of the players, italy is still very far behind the other favorite teams in the world cup Qatar.
2 failed World Cup qualifiers clearly gave disappointment to football lovers, especially with the status of the Euro champions there, making this a little distrustful.
But as you said, this is football anything can happen and now they have to watch at home about this championship.
There is nothing wrong with their players because regardless of what players they all almost have names that are quite capable but sometimes famous names are not able to bring them to achieve maximum results.
