Not directly piracy, but maybe you can find a version or similar one either on fearlessrevolution or MPGH. Without more info these are just guesses though.
Ok, I'm just gonna be specific. Mods can delete it if it's against the rules, but as you rightly imply, being circumspect about it isn't working.
Searching for a Cheat Engine table for the game (FIFA Manager 14 with the 2023 update mod. Holds up surprisingly well!) was actually how I was reminded of the old trainer Megatrainer XL, which is what I originally used for free a decade and more ago when the FIFA Manager games were new.
They call it Plitch now, though, and apart from the "extremely stingy freemium" part, it doesn't even work with the FIFA Manager 23 executable and Megatrainer XL, having been a rougher but otherwise much more forgiving piece of software, probably would. The part that makes it piracy is that they still retain the rights to the superior product they've since abandoned..
The same comment on the fearless forums also suggested its sister Megatrainer EX in their comment last month. They didn't post a download link, though and I don't know if that's even allowed on the fearless forums 😕
