This is not good, not at all.
Real are ageing out overall. Multiple huge retirements soon. Even a few of the ones I will list below are soon 30 or 31 (Rudiger, Cuntois, Alaba, Carvajal).
The will be buying massive new players.
Here are the only 30 (Alaba and Cuntois, not that 30 matters for a GK, and the soon rapidly in decline Carvajal, who simply must be replaced this summer or next IMHO) and unders ATM who are good to great on Real:
Thibaut Courtois
Éder Militão
David Alaba
Antonio Rüdiger
Ferland Mendy (they are not satisfied)
Daniel Carvajal (starting to age out now)
Aurélien Tchouameni
Federico Valverde
Eduardo Camavinga
Vinicius Junior
Rodrygo
Marco Asensio (meh and supposedly being sold)
2, 3 years from now or so, only the 8 (counting Mendy and a GK) in bold will still be there and not at nearing or actually ageing out levels. Pretty crazy.
