Michael Duberry says St Johnstone's players have written themselves into the club's folklore after booking a place in the Scottish Cup final for the first time.
The Perth-based side were trailing 1-0 at half-time but came from behind to beat Aberdeen 2-1 at Ibrox on Sunday courtesy of a double from their leading goalscorer Stevie May.
The Saints had lost in each of their eight previous appearances at this stage of the competition dating back to 1934.
Former St Johnstone defender Duberry praised the club's players for finally overcoming their semi-final jinx, insisting it is a remarkable feat for the Scottish Premiership minnows.
"When I was there that was my aim - to get to the club to their first cup final," Duberry told skysports.com. "Now every one of those players have written their names into the St Johnstone history books as the first set of players to get to a cup final.
"It's a massive achievement and, fair play to them, everything they get from this point on they deserve.
"I've played in a semi-final for the club myself when we lost to Motherwell 3-0 (in 2011). It was heartbreaking, it was horrible, but these lads have overcome that hurdle which has been over the club's head for so long now.
"To get to the club's first ever cup final in what I think is the first full season that this management team have had is amazing.
"They showed tremendous character (to come back from behind) and words just cannot explain what they have done and how big an achievement this is for the club."
Duberry spent 18 months at McDiarmid Park and became a fans' favourite after signing for the club following his release from Wycombe Wanderers in 2010.
The 38-year-old, who announced his retirement from professional football earlier this season, said he was delighted for the club's supporters and revealed he will make every effort to attend next month's final against Dundee United.
"I'm so pleased for the fans and everyone associated with the club," said the former Chelsea and Leeds United defender. "I'm going to look at my diary and hopefully try and free the date up so I can get there and be a part of it myself."
