Eight years ago Tate was part of the team which needed to beat Hull on the final day of the season to avoid relegation from the Football League.
Now he is heading for an appointment with the big-time.
Defender Tate, 28, admitted: "That game in 2003 was the most important I've ever played in. It was the day that saved Swansea City.
"The consequences of losing would have been miles more important than losing to Reading on Monday. It would have been devastating.
"The club would have gone out of business.
"I've probably watched the video of that game 20 or 25 times - more than any other game in my life.
"To look back at where we were then and think where we're heading now is just unbelievable.
"There are very few fairy stories in football but this is one of them and to play a small part has been brilliant."
