We continue our countdown of the greatest 30 players to have turned out for the Scottish giants.
Number 25 in our countdown of the greatest 30 Celtic players goes to a prolific striker of the Jock Stein era who was simply a goal machine for the club.
John Deans joined the Bhoys for £17,500 in 1971 after making his name as a goalscoring centre-forward at Motherwell, but he also a arrived with a reputation as a controversial player prone to disciplinary problems.
However, Stein ironed out the flaws in Deans' game and turned him into reliable and regular source of goals, something apparent from the forward's very first game for the club, in which he netted in a 5-1 win over Partick Thistle.
Forming a lethal partnership with Kenny Dalglish in attack for the Hoops, Deans won the league and cup double in his first season at the club, the first of six trophies he would win is his five years at the club.
There was a bleak moment early in his Celtic career, however, as he achieved the dubious distinction of becoming the first player to miss a penalty kick in a shootout in European competition when he was the only player to fail to score in the European Cup semi-final defeat to Inter Milan.
He recovered well from that setback, hitting a superb hat-trick in the 6-1 demolition of Hibernian in the Scottish Cup final less than a month later and helping to fire the side to an eighth successive league title.
A short, stout striker, Deans was a considerable physical presence in attack and had seemingly limitless energy, traits which served him well during his time at Parkhead.
By the time he left Celtic for Luton Town as a 30-year-old in 1976, he had scored 124 goals in 184 appearances for Stein's side and had become a recognisable staple of a hugely successful period for the club in the first half of the 1970s.
