Does Redknapp do it? I totally agree btw.
Football still has this attitude of "they're young lads and can do what they like with their money", but as you say, they're very highly paid athletes now, it's no longer a case of Jackie Milburn doing a morning down the pit, playing at SJP, then going for a few in the local and smoking a pack of 20.
I dont think Redknapp has a ban on it, but he has a very dim view of his players drinking. Ferguson too, there's an interesting piece in his autobiography about how one of his first major moves at Old Trafford was to clear out some of the heavy drinkers. McGrath was a fantastic defender but Fergie saw him as one of the ringleaders of a drinking culture and he was quickly out on his arse.
For me, its a combination of drinking AND the nagtive attention you will inevitably attract being a footballer and out on the lash at 2am.
A few pints in a quiet bar is one thing, sloshing it up on Collingwood Street is quite another.
This is the thing, it's not easy to successfully enforce. Yes, it's easy to ban/fine them or whatever if they're seen in a nightclub at 2am but what's to say others aren't getting plastered at a friend's house, or in a bar and not spotted?
