Unfortunately my viewership of La Liga has dropped off massively this season, despite paying for Eleven Sports haha.
One thing I would say is he has had a very good start to the season, and as A4TT said he was called up to the Spain squad recently and may be seen as a long tern replacement to Pique in the NT. Whilst this sort of signing is probably worth the risk for us (a young, developing talent, who is probably more talented than all our CBs combined). One caution I would add is that his new-found prominence was largely due to a very strong start by Espanyol, but their form has nose-dived recently so it’ll be interesting to see if his fame stays around. I also think Madrid have a buy-back clause making it a difficult signing. However, Madrid letting go of a player from their youth team is usually a sure sign that they will become a very good player .
All in all though I’m so out of sync with la liga and football at the moment so I really can’t offer any meaningful insight. I now only watch Real Betis/Barça and some derby games due to it not being so easy to access
@AbouCuellar will know much more about him than me
