Evra accused the then-Liverpool striker of racially abusing him during a Premier League game at Anfield in October 2011 which ended 1-1.
The Uruguayan, now at Spanish champions Barcelona, was handed an eight-game ban and fined £40,000 for his actions but Liverpool were unwavering in their support for their star striker.
Liverpool’s players wore t-shirts in support of Suarez 24 hours after he was found guilty of the incident in a league game against Wigan Athletic; an action which irked black footballers at the time.
Former Liverpool defender Jamie Carragher, who backed Suarez at the time, recently apologised to Evra for publicly backing his teammate.
In the build up to Sunday’s league game between England’s most successful clubs, Evra has revealed that Liverpool CEO Peter Moore recently sent him a written apology concerning the incident.
"First of all I was really pleased with Jamie Carragher apologising and then I received a personal letter from Peter Moore and I was really touched by it," Evra told Sky Sports ahead of Sunday's clash between the Premier League leaders and United at Anfield.
"He said he hopes it's never too late, because this incident happened nine years ago. Three days after the show [he made contact] and I said thank you very much, this letter has touched my heart.
"I was really disappointed at such a big club like Liverpool to support [Suarez], but now I can see it’s real, honest people working at this club and I get even more respect for Liverpool because I can see they are fighting this problem with the human race.
"I was really pleased and I just said I hope they do not win the league, but that was three months ago! Even though there is a big rivalry between us, it shows Liverpool is a top-class club."
