Manchester United players will face Everton with the threat of the "hairdryer" today.
United allowed Everton to draw 4-4 in the corresponding game last season, which eventually saw them surrender the title to Manchester City.
Everton's astonishing comeback was followed by defeat at City the following week, allowing their rivals to seize an initiative that, despite that amazing last-day drama, they did not lose.
"If I had to pick out one single match where we lost our title it would have to be that game," Ferguson told United Review.
"What I can say is that it won't happen again - or if it does, then put it this way, they will feel the full effect of the hairdryer."
