The Red Devils were leading 4-2 heading into the final 10 minutes of the clash last April before late goals from Nikica Jelavić and Marouane Fellaini salvaged a draw for the visitors.
The Red Devils currently lead the Citizens by nine points – but Ferguson has warned the 19-time champions to expect a difficult match against David Moyes’ side.
“It’s a tough game on Sunday,” Ferguson said.
“We were 4-2 up with seven or eight minutes to go. It was unexpected and we have to anticipate the unexpected in the run-in. That was a bad blow for us and it cost us the league.
“Everton are very experienced and, if you look at their record, they’ve only lost three games this season [the same number as United]. They’re obviously hard to beat.
“But the team is playing well, I’m pleased with their form and I’m pleased that the players we’re changing around, when I’m making different team selections, are buying into it well.
“They’re all contributing in their own way and that gives us a better chance in terms of dealing with the various competitions we’re in now.”
