The odds may be stacked against the Arizona Cardinals in Sunday's Super Bowl but the one man who could steal it from Pittsburgh is former supermarket shelf-stacker Kurt Warner.

The 37-year-old quarterback, a veteran of two Super Bowls with the St Louis Rams as a winner and loser, leads the unfancied Cards who are 9-4 against with Skybet to cause an upset against the Steelers who are going for a record sixth win in the NFL's big end-of-season finale. Warner failed to get a game with the Green Bay Packers in 1994 and had to turn to the night shift at a Hy-Vee supermarket in Cedar Falls, Iowa. He kept his game sharp by playing indoor Arena Football with the Iowa Barnstormers and then found himself back outdoors in the NFL Europe League with the Amsterdam Admirals.

That proved the springboard back into the NFL and in 1999 he led St Louis to a Super Bowl win and he was voted the game's MVP.

The tough part now is to lead Arizona, who won only nine of 16 regular season games, but caught fire in their three play-off contests, past Pittsburgh, who were 12-4 this year. The Steelers, winners of the famous Vince Lombardi trophy in 1975, 76, 79, 80 and 2006, are seven-point favourites to lift the silverware again in Tampa Bay on Sunday night against the Cardinals, who have never reached the Super Bowl before.

But Warner has run into form in the play-offs and has the skill and experience to topple Pittsburgh and deny them that record.

Fans should also stay up to watch Bruce Springsteen and the E Street Band perform during the half-time show.
