I've always thought that the best way of dealing with the issue of time-wasting when goals are scored would be to amend the rules as follows: Team X score a goal; the referee retrieves the ball and makes his way at his own pace to the centre-circle and places the ball on the spot. When Team A are ready, they kick-off.
This would prevent excessive and frankly tosseresque goal celebrations viz. last week's winner from the Car-toons when they realise halfway through their mutual masturbatory backslapping that eleven men are bearing down on their 'keeper at the other end of the pitch.
Problem solved!
