Personally, I think its a combination of being caught bang to rights (even though we know it happens) combined withe the fact you already have a youth ban, which means a potential transfer ban, rather than a paltry fine.
Sounds to me that Saints can prove you tapped him up in a really obvious way. Not good for FSG, with Liverpool and Roma being poles a part on a fee for Salah too
I could argue that its a last ditch effort by Southampton to hold unto their player. However we have previous on tapping up players and I think the Club is trying to save face here as the last thing we need is a transfer ban. Rather embarrassing tbh.
