Pointless. Most weeks he has angry reactions towards a linesman or ref, which has zero impact on any decision making, other than increasing the chance of a yellow card. He should be able to control this, but even if we accept this this is part of his game, surely our captain or other senior players should be straight over to pull him away from the referee.
If he unnecessarily gets to 5 yellows and misses a key game, it'll be disappointing to say the least.
