Magus
Player Valuation: £8m
Not condoning it but my point is to people believing these rumours (I know you don't) is why would Koeman get sacked or agree to mutual termination for goosing a secretary? Same way Rooney won't get sacked or any other player for having a fling, it's their personal life, can probably get a bollocking from the powers that be for it getting out to the public but how could they legally sack him over it?
Gross misconduct I would imagine.
I once worked at a place where this scenario actually happened, and the fella got the bullet in the end although it wasn't done via a public disciplinary procedure.
