Firmino was clearly upset after being shoved into the advertising hoardings by Holgate, with lip-reading experts reportedly claiming that based on television evidence the Brazilian appeared to say: 'Es maluco, filho da puta?' Translated it means: 'Are you insane, you son of a b***h?'
That some Liverpool fans would consider branding Holgate a liar-before the matter is investigated, even-suggesting he might have made it up to get a Liverpool player in trouble, is disappointing.
Liverpool and Everton assist Merseyside Police with probe into racist tweets
Merseyside Police confirmed on their official Twitter account on Sunday that they are investigating racist comments made on social media on the day of the match and they are liaising with the two clubs.
Everton hasn't commented on the issue beyond Allardyce's remarks. Holgate had to be restrained by several team-mates and appeared to complain to the referee, Robert Madley, that a racist term had been used. Madley spoke to the fourth official, before play continued.
Liverpool said late Friday that the club would "fully co-operate with the relevant authorities to ensure the facts are established in a thorough manner".
"I'm telling you nothing until whatever systems are used to find out exactly what happened or didn't happen", the Everton manager said. I'm here to talk about football. "I have told the Director of Football to sort that out". "I will let the director of football [Steve Walsh] deal with that".
He said: "I heard about something but I can't say anything so far. I had information that something has happened but I don't know what happened". That's how I understood it at first.
Anything more-what Holgate might have heard or thought he heard-is conjecture.
"Then after the game. the fourth official informed me but it wasn't that I really got it (what was happening)".
