Suarez was handed an eight-game ban by the FA for racially abusing United defender Patrice Evra.
Ferguson said: “The matter is over and I think we’re satisfied they’ve found the right decision.
“It’s not about Manchester United and Liverpool at all. This is an individual situation where one person was racially abused.
“It doesn’t take a lot to remind everyone that this is the biggest derby game in the country. It’s never needed anything to light the powder keg.”
Evra was handed a four-match ban three years ago for failing to convince a panel he had been racially abused during a bust-up with Chelsea groundstaff.
But Ferguson insists that Liverpool are wrong to question the Frenchman’s credibility.
Ferguson said: “Our support of Patrice was obvious, right from the word go.
“Patrice got that suspension for the incident down at Chelsea when no-one was there, just a groundsman and our fitness coach.
“We had to wait two weeks for the evidence. We were quite astounded ourselves.”
