HE won seven trophies in Glasgow and played a crucial role in the famous win over Barcelona in 2012.
But that heroic performance for Celtic at Parkhead was eclipsed this season as he topped off his latest stint in football with his first European winner's medal.
Fraser Forster is now unemployed at the age of 37 after being released by Tottenham Hotspur - less than two weeks after lifting the Europa League trophy in Spain.
The former Celtic goalkeeper, who enjoyed two spells in Scotland, now has a decision to make on his future in the game after ending his time with Ange Postecoglou's side.
Forster made 34 appearances for Spurs in three years after being brought to the club in 2022 as backup keeper.
He played 20 times in his first campaign with the club but was handed just one appearance in his second - and his first under Postecoglou.
But this season he was brought back into the fold once again after injuries to Guglielmo Vicario left him out of the side.
Forster was between the sticks in four Europa League ties and nine domestic fixtures.
He even faced his old rivals Rangers at Ibrox in December but failed to keep a clean sheet after Hamza Igamane hit the back of the net to make it 1-0.
But Forster had plenty of clean sheets against the Light Blues earlier in his career, having kept them out as many as seven times for Celtic.
The towering Englishman is considered by many to be the Hoops' greatest goalie in recent decades.
His first spell in Scotland was over a period of four years in which he had back-to-back loan stints before joining on a permanent deal from Newcastle for £2m.
He left for Southampton in 2014 for £10m and returned north of the border on another loan in 2019.
During that first spell he earned the nickname La Gran Muralla (The Great Wall) thanks to his heroics in the aforementioned European upset over the Catalan giants.
The Hoops narrowly lost at the Nou Camp but at Celtic Park he was the star of the show, repelling the Spanish armada wave after wave of attack.
His exploits at one end allowed for Victor Wanyama and Tony Watt to write themselves into the history books at the other end, as Celtic recorded a famous 2-1 win over Lionel Messi and Co.
The Argentine superstar would later go on to say of Forster that night: "There was one game in Scotland when he was not human, it was the best goalkeeping performance I have seen."
And after the game, Forster made sure it was he who ended up with Messi's shirt.
Forster won four league titles, two Scottish Cups and one League Cup during his time in Scotland.
He was voted Celtic's Players' Player of the Year in back-to-back seasons - in 2013 and 2014.
