Stevo is correct on this one - the referee should just play on. Any player other than the goal kick taker may play the ball once the ball has left the penalty area. The fact that the keeper didn't take the goal kick and was in his own box when the ball returned entitles him to handle it as normal.
Cheers Sparkey - really enjoyed reading this thread; educational and amusing (especially Aber's replies - how's it going butty?). And before you ask - was absolutely clueless and didn't get a single answer correct!
No probs Cartoon - just a little diversion from our current crap on the pitch is a relief - glad you enjoyed it pal.
I did Sparkey - as for the 'crap on the pitch', at least you have put real distance between yourselves and the relegation spaces and can push on next year; was also a lot more passion evident in the side against Brentford. Good luck for the rest of the season.
