Muhammad Zulfahmi bin Mohd Arifin (born 5 October 1991) is a Singaporean professional footballer who plays primarily as a defensive midfielder for Singapore Premier League club Hougang United and the Singapore national team.

[4] He managed one further start and a substitute appearance on his return as LionsXII won the 2013 Malaysia Super League.

[5] He marked his return to the starting line-up on 22 March by curling a free kick into the PKNS net to score his first LionsXII goal.

[7] Zulfahmi signed for the Cheetahs ahead of the 2017 Singapore Premier League season, joining former coach Phillipe Aw.

After playing 60 minutes in a 2–3 friendly defeat to Port, Chonburi offered him a contract which is only slightly higher than what he received at Hougang.

[8] Zulfahmi became only the third Lion to play in the Thai top tier, after Hassan Sunny and John Wilkinson.

Suphanburi's coach Adebayo Gbadebo had watched videos of Zulfahmi's previous games before expressing an interest in signing him.

[13] Zulfahmi suffered a difficult 2020, playing just 8 of Suphanburi's 15 league matches in a disrupted season, having returned to Singapore in August to be with his ailing mother, who later died from breast cancer.

He will play alongside his international teammate, goalkeeper Izwan Mahbud, who joined the club in September.

[16] Along with Hariss Harun, he has been identified by national coach Bernd Stange as the future of Singapore's midfield.
