Dejphon Chansiri, a Thai businessman born in Bangkok in June 1968, became the owner of Sheffield Wednesday in 2015 with a promise to take the club back to the Premier League. A decade later, his tenure ended when he placed the club into administration in October 2025, triggering a 12‑point deduction and a three‑year ban from English Football League ownership. This article examines what happened, his background, businesses, family, and the financial picture that remains largely unclear.

Who Is Dejphon Chansiri? – Biography and Background
Early Life and Family
Dejphon Chansiri was born in Bangkok, Thailand, on 3 June 1968. He is part of the Chansiri family, which founded and controls Thai Union Group, the global seafood company behind brands such as John West and Chicken of the Sea. His father, Kraisorn Chansiri, is described as the founder of the business, and the family has been ranked among Thailand’s wealthiest. The Athletic and BBC Sport have reported on this background.
Entry into Football
In January 2015, a consortium led by Chansiri acquired 100% of Sheffield Wednesday from Milan Mandarić for £37.5 million. He immediately set a target of reaching the Premier League by 2017. That ambition was not realised, and the subsequent years were marked by financial losses, fan protests, and regulatory scrutiny.
His age (57), nationality (Thai), and family connection to Thai Union are well‑established. His educational history is not publicly recorded. No verified information about his early career before football ownership exists in the sources provided.
Ownership Style and Controversy
According to a 2025 report by The Athletic, the club was run in a highly centralised way, with Chansiri as sole shareholder and no functioning board structure. This lack of oversight contributed to the financial collapse that culminated in administration. The administration also affected Hillsborough, the club’s stadium company, as noted by The Guardian.
Dejphon Chansiri Net Worth and Businesses
Net Worth: Family Wealth vs. Personal Fortune
Publicly cited net‑worth figures for Chansiri are inconsistent and almost always refer to the Chansiri family’s wealth rather than his personal assets. One source, citing Forbes‑linked reporting, placed the family’s net worth at US$575 million in 2020. However, neither Dejphon Chansiri nor his representatives have disclosed an audited personal net worth. The Sheffield Wednesday News and Football League World note that separating his personal finances from the family fortune is not possible with publicly available data.
Business Interests
Before his football involvement, Chansiri was reported to have interests in construction and property in Thailand. BBC Sport stated that he made his fortune through canned tuna and the wider family seafood business. He is also recorded as a director of 19 Thai companies, many of which are small, loss‑making, or dormant, according to the SWFC Trust’s analysis using Companies House data. In the UK, he owned or controlled Elev8 Clothing Limited and D Performance Limited. A claim that he owns D Taxis in Sheffield is less well substantiated.
Director Appointments
An official list of his current and past directorships is available on the Companies House register. His LinkedIn profile also lists his role as former chairman of Sheffield Wednesday FC.
No credible source provides a verified personal net worth for Dejphon Chansiri. The figures that circulate online typically conflate his wealth with that of the wider Chansiri family. The available evidence from Thai company filings does not indicate a level of personal wealth that would have sustained a Championship club without external family support.

Why Did Dejphon Chansiri’s Ownership End in Administration?
The Guardian article describes a pattern of financial mismanagement, fan protests, and failure to meet EFL regulations. Chansiri’s Thai businesses provided little cash flow, and the club accumulated debts. The administration move was seen as a last resort to avoid liquidation.
