Ivan Golac, the man who led Dundee United to Scottish Cup glory in 1994, has warned his old team not to worry about Celtic at Hampden.
"You have to believe you can win it," Golac told the Evening Telegraph.
"In 1994 we always felt we could do it and our preparation was different because we were not interested in what Rangers were going to do.
"If you are talking about opponents too much, you are just going to take the sting out of players and worry them."
And Golac, who arrived at Tannadice in the summer of 1993 for a 19-month spell in charge, thinks all the pressure is on Celtic on Saturday.
"They are a club I have a lot of time for, but I tell you, this has become a very difficult game for Celtic.
They are one of the big boys and, along with Rangers, are one of the sleeping giants of European football.
"They should do a lot better in Europe and the kind of success they have in the league and cups in Scotland is the way it should be.
"This season, though, they are in danger of not winning a domestic trophy and that would be a terrible thing for them.
"It also means they will be feeling the pressure and, after losing the league to Rangers in the way they did last weekend, it is going to be extremely difficult for them.
"They also know their manager is leaving and that could affect them, though, having said all that, the wounded lion is always dangerous and they are a club with so much pride they won't be easy to beat."
