I agree, however he's doing it for the same club that has a vested interest in his pay being enough to actually get him to agree to retire on less money.
If he was going to another club I wouldn't question if 300k was 'market rate' for the role.
Yeah just guesswork without a frame of reference. We don't have any idea how much others are being paid to do similar work.... or really what the **** the work is
For an elite player with a broad appeal it seems realistic that they'd get a decent pay packet but its probably is topped up with a bit of extra good will...
