Oh yeah I understand your point, there is no guarantee. I think people comment with the understanding or assuming he hasn’t had a stinker.
There were periods that we could have sold Davies and instead ran his contract out. That’s not so much for his decline but the clubs decision making. But yeah, I think Yakubu is a good example.
11m for him, sold him for something like 2.5 despite him proving he was worth it, but over 3/4 years, injuries had an impact (anyone can get an injury).
I think people are desperate for us to be more proactive in younger players, if one gets 30/40 appearances within 2 years, they won’t have decreased in value.
But yeah. There’s no guarantee but think it’s like that with any signing. Everyone just assumes they’re gonna be a hit or a good signing. Not just Everton fans, just genuine football fans in general!
