The FA Cup pairs together two sides that are meeting for the first time since the unsavoury affair involving Luis Suarez and United left-back Patrice Evra.
The Liverpool striker was subsequently banned for eight matches after being found guilty of making racist comments and Fergie does not want this to osculate into the stands thus starting another war between the fans.
Ferguson said: "As (Liverpool captain) Steven Gerrard said yesterday, there is a responsibility on the players to behave properly and also both sets of fans.”
"We want to make sure we are talking about the game, nothing else."
When asked if Evra would be playing, he added: "I am not getting involved in that.”
He went on: "It is a massive game for both clubs. There is a tremendous profile on it.
"I am confident. We want to talk about the game of football. It is something you want to look forward to. That is what I intend to do.
"Our fans were terrific there this season.
"The issue of clubs reducing the number of tickets for our supporters has been going on for quite a while now. It has become a convenient way of selling their hospitality.
"But the stewards have a difficult enough job as it is. We should be helping."
