Sir Alex Ferguson will take nothing for granted ahead of Manchester United's blockbuster FA Cup tie with Liverpool on Sunday.
Ferguson has an excellent record in the world's oldest cup competition, winning the trophy on five occasions.
However, last season brought one of his least favourite moments as United were dumped out in the third round for the first time since he arrived at Old Trafford in 1986.
Even worse, defeat came at Old Trafford, at the hands of a Leeds side who were trying to gain promotion out of League One.
So, with the standard of opposition far higher, and the rivalry just as intense, Ferguson has no intention of making life easy for the Merseyside giants.
"It was a bad result last season against Leeds, especially considering the rivalry between the two clubs," Ferguson told Inside United. "In hindsight I could have picked a stronger team. I won't be making that mistake this time."
