Everton are helping police after Brentford's Rico Henry and Ivan Toney claimed members of their family were racially abused in the Premier League match at Everton.
Henry, who scored the winning goal in Sunday's thrilling 3-2 victory at Goodison Park, took to social media after the game to call for the incident to be investigated.
"I never usually speak out on things that don't physically harm me or my family but to see my mom upset after being racially abused by a few Everton fans brought fire to my stomach!," he posted on Twitter.
"I will do anything for them & whatever it takes to get the small minority punished! This is not acceptable & must be investigated immediately."
After tweeting about the fireworks reportedly let off outside the Brentford team hotel, Toney added: "And for the man that racially abused my family Il (sic) do everything I can to get you the punishment you deserve!"
Everton responded to Toney's post with a tweet which read: "There is no place in football - or society - for racism. We are assisting Merseyside Police to ensure the individual is identified and dealt with appropriately."
The Toffees had defender Jarrad Branthwaite sent off in the 18th minute when they were 1-0 up at home to the Bees and then substitute Salomon Rondon red-carded in the 88th.
Everton, who have two games left, are still in the relegation scrap on 36 points, with Leeds United, who have one more match to play, on 35 and Burnley, with two to come, on 34.
Merseyside Police confirmed late on Sunday night an investigation had been opened.
"No matter what football team you support, there is absolutely no place for hate anywhere in Merseyside under any circumstances," Detective Inspector Catherine Cox said.
"Merseyside Police has investigated and successfully prosecuted so-called fans for racial abuse inside football stadia, and offenders have been handed football banning orders along with a criminal record for their behaviour.
"We will support the victims in this case and work with Everton Football Club to find those responsible and bring them to justice. Their views and their abuse is not welcome here in Merseyside, and they do not represent the overwhelming majority of football fans."
