Nobody would mate your having a laugh, just have a think what you just said. The ref then gives a penalty what would your team mates think?That's an incident where the ref would have to play on if he hasn't seen it, the officials referee the game on what they see. **
The Bamba incident was while the ball was out of play.
** for what it's worth, yes I would tell the ref i'd handled the ball (and I'm not saying that just to win the argument )
Bemba could have said “if you didn’t see it how can you book me”
