Team doesn't have any more or less youth than most other top teams really.
Madrid have Rodrygo/Vini/Tchouameni and sometimes Camavinga in the starting lineup, Bayern have Musiala and Davies there, Chelsea with RJ/Mount/Gallagher etc. Not really that out of line with top teams that there are some youngsters regularly playing, maybe Gavi/Balde/Pedri are a little on the younger side, but doesn't really seem an excuse for a huge humiliation just because you have a couple young players.
Laporta is trying to spread that narrative in order to hide his own shortcomings in the way he's dealt with this past transfer market but everyone should see through it as the team isn't overly young compared to European competitors.
We are the team that use the most U23 (or was it U21?) players in top 5 leagues based on a research I've read a few weeks ago.
If we finally remove Busi from the lineup (which most of us want) and go with something like
MATS (30); Bellerin (27), Araujo (23), Kounde (23), Balde (19); Pedri (19), FDJ* (25), Gavi (18); Dembele (25), Lewy (34), Raphinha (25)
* Can insert Neves instead of FDJ, they're same age and we'll probably sign a younger RB as well.
Then average age of first XI would be around 24,3 years (23,8 for outfield players). That's pretty young tbh.
According to TM average age for a whole 25-man squad is 25,4 years (4th youngest in La Liga) but ofc include oldies like Pique and Alba who are phased out of the team and are expected to leave alongside Busi. In comparision Madrid's average age is 27,4 years and they'll probably keep Benz and possibly Modrić and/or Kroos around for another year.
If we look at El Clasico lineups:
Madrid: Lunin (23), Carvajal (30), Militao (24), Alaba (30), Mendy (27); Tchouameni (22), Modrić (37), Kroos (32); Valverde (24), Benz (34), Vini (22) - average age 27,7 years (28,2 for outfield players as it's obvious Courtouis is their #1 GK)
Barcelona: MATS (30); Roberto (30), Garcia (21), Kounde (23), Balde (19); Pedri (19), Busi (34), Gavi (18); Dembele (25), Lewy (34), Raphinha (25) - average age 25,27 (24,8 for outfield players)
But rather than just look at difference in age/experience I believe main difference between two teams is Madrid's veterans are still performing on a good level so they don't need to depend as much on the youngsters who get more time to develop in a more healthy environment. They were patient with Vini for 3 years. We'd give up on him long time ago (and as we I mean the club not fans who would obviously write him off after first bad game). Here likes of Pedri, Gavi and Ansu before his injuries were thrown into the water because we've had no other options. And yet we have folk complaining they're incosistent blabla not realizing how young they really are and taking much more responsibilities on their shoulders than they should.
Average age of Bayern's lineup last night was 26,2 years. They had a young defense (23 years) and Musiala but surrounded them with Kimmich, Goretzka and Gnabry who are all in their prime years (27) and Mane at 30. And this are exactly the players (age wise but ofc also based on their quality) that we lack.
As said in another post our players are either on a decline (been there for years except Lewy ofc) or youngsters still developing and earning experience. We don't have any established player in that 26-29 range that would've been at the club for a few years. FDJ and Dembele are the closest to that and for different reasons neither of them is seen as a leader of the team and are unlikely to become one as well when the old guard is finally gone. One of the reasons why we've signed Raphinha, Kessie and Christensen and why we're now looking at Neves for example.
But ofc they can fit age/experience criteria but still fail because they're 1. not good enough or 2. (which is more likely) because Xavi can't use all the new toys he wanted to sign in first place.
bit of a numbskull suggestion.
