I used to be a teacher in Liverpool. We used to play other schools and there was one bloke, Vic Christian, iirc who was a raving lunatic. He was the brother of the lead singer from The Christians. Basically you just let him have the ball else...
That sort of behaviour's best left to Johnny Foreigner old boy...as long as their second language is English and we don't have to listen to their native jibber jabber.
