A key member of Pakistan's World Cup-winning squad in 1992, where he was his country’s second highest wicket-taker behind Wasim Akram, Mushtaq also played in the 1996 competition. He was named one of Wisden’s five cricketers of the year in 1997.
He had two spells as Somerset’s overseas player in 1993-95 and 1997-98 and replaced the absent Saqlain Mushtaq at Surrey in 2002 before moving to Sussex, where he was named player of the year in his first season.
When Sussex won the county championship in 2003, Mushtaq took 103 wickets to become the first bowler in five years to capture 100 in a season.
2005 saw the leg-spinner continue his good form as his 80 wickets helped Sussex to secure third place in the championship.
But arguably his greatest season came in 2006 when he finished with 102 victims, taking 9-48 in the second innings en route to match figures of 13-108 in the victory over Nottinghamshire which sealed the title for Sussex.
He was appointed as Pakistan's assistant coach for the World Cup and took over the reins on a temporary basis after the death of Bob Woolmer.
He shone again with the ball in 2007, taking 90 wickets in the championship, and signed a new two-year contract keeping him at Sussex until the end of the 2009 season.
However, a persistent knee injury forced him to call time on his playing career towards the end of the 2008 campaign.
Mushtaq was subsequently recruited by the ECB as a spin bowling coach, and agreed a similar part-time role with Sussex in 2009.
Sussex granted him a testimonial the following year in recognition of his service to the club.
