John Hartson enjoyed a glittering career, playing alongside some legendary figures for the likes of Celtic, Arsenal, West Ham and Wales.
The striker is most fondly remembered for his time at Celtic Park, during which he scored 109 goals in 201 appearances.
Hartson has now compiled a greatest XI of players who he featured alongside, and two Celtic legends made the cut.
The first was Bulgarian midfielder Stiliyan Petrov, who Hartson selected in the middle with Frank Lampard. Speaking to BBC Sport, the Welshman said: "I absolutely loved playing with Petrov at Celtic. He had a ridiculous work ethic, he trained as he played and gave his maximum every day.
"He started at right-back under John Barnes and almost left the club. Then Martin O'Neill came in and Sitilyan became a massive part of the team. He could tackle, get up and down, was technically excellent. Hristo Stoichkov is on record saying Petrov is the greatest ever Bulgarian footballer, which is some praise."
Unsurprisingly, the front two is comprised of Henrik Larsson and Dennis Bergkamp. Of the Swedish striker known to Celtic fans as the 'King of Kings', Hartson said: "There was nothing Henrik couldn't do. His statistics are through the roof - 242 goals in 315 games for Celtic. He did it in World Cups, European Championships.
"A phenomenal goalscorer, incredible work rate, and everyone knew at Celtic that he was our best player. He won us so many games. Great in the air, deceptively quick and could get across people. Just an outstanding player."
Despite also including such legends as Ryan Giggs, Frank Lampard and Rio Ferdinand, Hartson referred to Larsson and Bergkamp as "The two greatest talents I played with".
