The exact same logic, with almost the exact same words, was used to justify countless previous failed signings that got us into this state.
In all seriousness, I don't understand the thought process that lead you to type those words unironically. Is it that you've forgotten the circumstances that caused us to make all those buys and don't see that it's the exact same situation with a different player subbed in? Do you for some random reason think Casemiro will be an exception in a way those other players whose purchases were backed with the exact same process, confidence and logic weren't? Or do you not accept that each one of those failed purchases set us back further than simply signing nobody in that moment would have?
It genuinely baffles me that people can be on a forum where we discuss the issues that got the club into this mess day after day and yet immediately jump into the same pattern of mistakes again with zero self-awareness, apparently having taken in nothing.
