Gary Neville lambasted Gabriel Martinelli for his conduct late on in Arsenal's goalless Premier League draw with Liverpool.
The Gunners forward sparked a melee after throwing a ball at and pushing Northern Irishman Conor Bradley when he was down on the pitch holding his knee after suffering an injury.
Martinelli was booked along with Ibrahima Konate, who was one of several Liverpool players to react furiously, while Bradley was eventually carried off on a stretcher.
Speaking on Sky Sports, Neville expressed surprise that Liverpool's players had not confronted Martinelli in a stronger fashion.
"I'm absolutely fuming with Martinelli," he said. "I don't know how the Liverpool players didn't go over and absolutely whack him and take a red card. Absolutely disgraceful that."
Neville's fellow pundit Roy Keane echoed his comments and called for Martinelli to apologise.
"I didn't like it at all," said the Irishman. "We know football, we know players' reactions. First of all throwing the ball on him, standing over him and then he's got a little knee in him, he's trying to force him off.
"I'm surprised the Liverpool players didn't react to Martinelli a bit more. I think Martinelli, with that behaviour, is an absolute disgrace. Not good scenes. Hopefully Martinelli will have a look at it and hopefully apologise for it."
Keane praised Liverpool for their performance and believes Arsenal's tentative display could bode ill for their title hopes.
"You keep a clean sheet, you take a point, they're the positives, but Liverpool kind of dominated the game," said Keane. "OK, they had no cutting edge but I think it was the way Arsenal didn't go and take the initiative.
"There was a little bit of tension in the stadium and obviously that will get worse the latter part of the season, so that'll be a worry, but all credit to Liverpool the way they dominated possession.
"They showed a bit of fight, they showed a bit of swagger, that they are champions."
Reds midfielder Dominik Szoboszlai felt Liverpool sent a message with their performance, saying: "We faced an unbelievable team but I think we showed again today why we became champions last season.
"This was a step forward after the recent weeks and we showed again that, even against a team who is top of the table, we can compete and we take it with us for the next weeks."
