He's 22 years old, I simply believe he did not think for a second that someone would 'post' his picture. I bet he hasn't got a marketing degree and know the importance of marketing etc at 22 years of age.
He messed up, he knows it now.
I thought straight away this comes back to the club and his induction at the club, these young guys surely must have had on day 1 (not a training session) a class room session re club history (both clubs), why they merged, where the club is heading, their role, marketing the brand, their role in that, about only be seen in club colours in public, never bringing the clubs name into disrepute etc etc.
If the club did and does all that and more, Laurie stuffed up, 1st warning for him.
