We continue our countdown of the greatest players ever to have turned out for the Bhoys.
After Tommy Gemmell's inclusion at number 28, there is another Lisbon Lion at number 27 in our countdown of the greatest 30 Celtic players.
Stevie Chalmers joined the Bhoys as a 23-year-old in 1959 and from the very first moment he arrived at Parkhead he displayed the raw pace and ability to finish that would serve him so well in a 13-year career at the club.
Like Gemmell, the forward's career was changed by the arrival of Jock Stein as manager in 1965, as were the fortunes of the club as a whole.
Stein recognised that the player's clever runs and movement in the frontline gave him the ability to both score and create goals, and under the new manager Chalmers became an integral part of the Celtic team.
Although he hit a blistering second-half hat-trick against in a 5-1 victory over Old Firm rivals Rangers in 1966 and scored a superb solo effort against the same opponents in the 1969 Scottish Cup final triumph, there can be no question over what was Chalmers' career highlight.
After Gemmell had equalised against Inter Milan in the 1967 European Cup final it was the striker, with just five minutes remaining, who scored the winning goal as Stein's Lions became the first British side to win Europe's highest honour.
In total, Chalmers racked up 228 goals in 405 matches for the Glasgow side, winning 12 major trophies under Stein.
His individual place in the club's record books is sealed not only by his scoring of the most important goal in Bhoys history, but also by the fact that he still stands today as Celtic's fourth-highest goalscorer of all time.
Amazingly, he was capped only five times by Scotland, something due mainly to the competition of a certain Dennis Law for a starting spot in attack, although he still managed to find the net three times for his country.
A broken leg sustained in the 1969 Scottish League Cup final effectively ended his Celtic career, but by that point Chalmers had done more than enough to cement his place as a true legend of the club.
