One thing I didn't realise is that in this WC, they are adding time on for the goal celebrations and how long it takes to kick off again. I wouldn't really wish to stop that or make players take corners overly quickly (although some corners take forever whilst the ref. sorts out all the jostling in the box). Not really a fan of the stop-clock, as the ball being out of play is part and parcel of football. That's why we have throw-ins, corners, free kicks, penalties, goal kicks, etc. However the refs being more conscious of deliberate time wasting is definitely a step in the right direction.
