Liverpool manager Jurgen Klopp refused to be drawn on an allegation of racism by Roberto Firmino but the club issued a statement after their 2-1 win over Everton in the FA Cup.
A clash between Firmino and Everton’s Mason Holgate will be included in referee Bobby Madley’s report after the Toffees raised the incident with match officials.
Press Association Sport understands the Goodison club made representations after the final whistle following the 40th-minute altercation at Anfield.
Liverpool also issued a statement.
“The club and player will fully co-operate with the relevant authorities to ensure the facts are established in a thorough manner if deemed necessary or requested,” said a club spokesman.
“While that process is ongoing we will not be making any further comment.”
It is understood Firmino was not asked for his view on the incident immediately after the match but is prepared to give a statement to the FA should a request be made.
“I only heard about something but I can’t say anything about it because so far I couldn’t speak to anybody and I think, from now on, first of all the club will answer,” Klopp said.
“I don’t really know anything about it.
“I misjudged the situation obviously completely, because I thought it was about a Holgate foul.
“In the end there was no foul, no yellow card, nothing. I didn’t get it to be honest – there was a throw-in, was it?
“I didn’t understand the whole situation after the game. I got information that something obviously happened, but I can’t say anything about it.”
The row overshadowed a dream debut for £75million new signing Virgil van Dijk who scored the winner in front of the Kop on his debut.
James Milner’s penalty had given the hosts the lead in the first half only to be cancelled out by Gylfi Sigurdsson’s counter-attack goal.
