and that should have been a penalty
Gerrard was going for the ball, Gallas was too late
FWIW though, it's about time Arsenal got a fair suck of the sav regarding big game decisions

normally we get the raw end of the deal

which is why , now for than ever, we need video citing post match to punish flagrant acts of unsportsmanlike charlatanism.
