We continue our countdown of the greatest 30 players ever to wear the Bhoys shirt.
Following Lubomir Moravcik at number 30, number 29 in our list of the greatest Celtic players goes to a man who may not have the trophy haul to match many of the club's other greats, but who was a key player for six years at Parkhead.
John Collins joined Celtic in 1990 from Hibernian, becoming the Bhoys' first ever million pound player when he was signed by Billy McNeill to bolster the midfield.
The boyhood Hoops fans endeared himself to the club's fans before he had even set foot on the pitch by choosing to join the club over arch-rivals Rangers, and one of his more notable moments for Celtic came in an Old Firm clash from which Bhoys fans were banned when he curled a free kick into the top corner to silence a stunned Ibrox.
Collins was a shining light in a dark period for Celtic; the club didn't even finish in the top two in the Scottish top flight until his final season and won just one trophy during his time, the Scottish League Cup in 1995.
However, that was no fault of the midfielder's, who forged a dominant partnership with Paul McStay and helped support the attack and drive the team forward.
After outlasting three managers, he left in 1996 to try his hand in France with AS Monaco, and he later played for Premier League sides Everton and Fulham in the latter years of his career.
Collins also had a distinguished international career with Scotland, scoring 12 goals in 58 appearances and playing for his country at Euro 96 and the 1998 World Cup.
Not content with his playing career for the club he supports, the 48-year-old still plays a large role at Parkhead today after returning in June 2014 to serve as assistant manager to Ronny Deila.
