I'm hugely skeptical of those websites, even the popular ones and I'm almost certainly guilty of using them myself but there's just no way they have this information. Who is leaking a players wage? The player likely isn't wanting that out there, the club aren't, so who is it? the only time it's conceivable is if it's a low wage and his agent is seeking a payday and a new contract that thr club arent keen on giving. The thing is, they claim to know every single players wages. It's just not remotely believable when you think about the level of private information they'd need to have but we all just accept it as truth for some reason.
But that's a different thing altogether, for arguments sake, accepting those figures to be true, 100k a week difference is nothing in the grand scheme of things, it's a nice bonus to save that but it's inconsequential in any of our thinking.
I love Ortega, best backup we've ever had and have no issues when he comes in but he's not in any way better than Ederson imo.
