Is it really that unneccesary to allow physios on to the pitch while continuing with play? Then only stop play if the physios give a signal that it's a genuine bad one, and by that I mean a stretcher is required, not he needs 20 seconds of magic spray applied.
Either that or retrospective action for incidents where its considered the player is taking the mick. But even then the odd incident will slip through the net.
Heard Carragher go off at somebody recently and whined we should just play on, even though it was a head injury incidentally I don't think his head was even touched but this is where we are screwed when a head injury guarantees a stoppage. Then the next day someone rightly pointed out that the physios are either in on this tactical feigning malarkey, or they are being mugged off by their own players. Just another modern game annoyance.
