Leeds United legend Eddie Gray has urged fans not to expect too much from their FA Cup tie at Manchester United.
It will be the first time in six years that Leeds have faced their bitter rivals.
Gray, who was in charge of Leeds when they last clashed with United, told the Yorkshire Post: "This time, it's unfair to be too expectant. The squad I worked with contained Premier League players but this is the biggest step-up for a League One club - the best draw you could possibly get but probably the most difficult as well. I'll be like most of the 9,000 supporters on Sunday - going there in hope rather than expectation."
