For example, 7 years ago.
Sometimes clubes pays release clauses but negotiate a easy way to paid it with the other club, I think this happen with Rodri.
But you got it. Imagine pay 60/70m in Cash for Kepa, a disaster.
I think there is a problem of point of view here.
Our visión about PL clubs in Spain is that you overpay almost every player that you buy.
A "decent" price for you is out of any market for, almost, any club of Europe.
We think you waste your money in a crazy way.
For example, with the money that City bought Laporte, we signed Ocampos, En Nesyri, Diego Carlos and Kounde.
Of course in your enviroment sign a player for 60m is a Day in the office but out of there is crazy.
The best young player are sign for the Best clubs before their 16.
Ansu Fati was playing for Sevilla and Barcelona made an offer to his father and he went there.
Ansu made his debut the last year and Barcelona renewed his contract with a release clause of €1000m.
Of course you could sign young player but It would be more a bet that a sign.
PD sorry all for my english but I am with my friene omicron playing chess and doesn't help.
