This time Luis Suarez has surely bitten off more than he can chew.
Liverpool's Luis Suarez is likely to be in trouble with the FA over the evidence illustrated in this photo.
Is this the moment Luis Suarez waved goodbye to the goodwill he had re-earned himself after last season's controversy?
After a season of sensational performances, including a last gasp equaliser for Liverpool against Chelsea, re-affirming his status at the Premier League's top scorer, people were actually beginning to talk about Suarez for football reasons.
Now he is back in the headlines for all the wrong reasons.
Former Liverpool stalwart Mark Lawrenson told the BBC: "He deserves a lengthy ban as there is no room for what he did in football."
He has form for it too, Suarez was banned in Holland for seven matches for biting an opponent, and as no action was taken by the referee over this latest incident, there is likely to be FA action.
It could even see Suarez miss the rest of the season, and at the worst, the start of the next.
What do you believe should and will happen to Suarez?
