im talking seconds Ross not a passage of play....!! now im getting defensive ...and backed into a corner lolI'm all for keeping the game flowing and always look to playing advantage when the game allows it. I've no problem with anyone trying to play an advantage in the penalty area, what I have seen too often is a referee trying to play advantage and then allowing too much time elapse before then blowing for a penalty. They then encounter problems trying to sell the decision as they've allowed play to go on for too long.
The question to ask yourself is, did the foul directly contribute to the miss (off balance player etc). If so bring it back give the pen plus disciplinary sanction. If the player has opportunity to reset his balance etc then play advantage player, but no second bite of the cherry if he doss not score, the fouling defender may still get a caution.
As said above, it more or less comes down to time.
The attacker player is the victim of foul play and should not be disadvantaged by the defenders foul.
