For a decade, Dejphon Chansiri was the public face of Sheffield Wednesday. The Thai businessman took full control of the historic EFL Championship club in 2015 with promises of Premier League football. By October 2025, his ownership had ended in administration, a 12-point deduction, and a ban from English football. This is the story of his rise, his family business, and the financial collapse that brought down a club.
Born on 3 June 1968 in Bangkok, Chansiri came from a family that controls the Thai Union Group, the world’s largest producer of canned tuna. But his personal business empire, detailed in public filings, tells a more complicated story of small, often loss-making companies. His time at Sheffield Wednesday became a case study in how a lack of board oversight and mounting debts can unravel a football club.
What happened to the man who once promised to lead the Owls to the Premier League? Fans, journalists, and regulators are still piecing together the full picture. What is clear is that his tenure ended not with a sale, but with the club being placed into administration and Chansiri being banned from the English Football League for three years. This article examines the facts known so far, from his net worth to his personal life and the timeline of the crisis.

What Is Dejphon Chansiri’s Net Worth and Business Portfolio?
Understanding Chansiri’s true financial standing is central to the story of Sheffield Wednesday’s collapse. The Chansiri family’s net worth was estimated by Forbes at US$575 million as of 2020, but this figure represents the collective wealth of the entire family, not Chansiri’s personal fortune. The family’s primary asset is the Thai Union Group, the world’s largest producer of canned tuna, which owns brands like John West and Chicken of the Sea.
Chansiri’s own business activities are far more modest. According to research published by the Sheffield Wednesday Supporters Trust, he is identified as a director in 19 active Thai companies. These businesses span real estate, construction, shipping, agriculture, aquaculture, hospitality, and asset management.
Are Dejphon Chansiri’s Thai Companies Profitable?
Public filings paint a concerning picture. Many of these companies are described as small, loss-making, or dormant. Some, like Seminai Co. and Chansiri A Co., Ltd., reported negative shareholder equity. The Trust’s analysis concluded that the combined profits from these businesses fall far short of the funds required to cover Sheffield Wednesday’s substantial losses.
Chansiri has personally invested an estimated £167 million into Sheffield Wednesday since 2015. Approximately £115 million is currently owed to him in unsecured loans. This means administration inflicted massive financial damage on him personally, as those loans are unlikely to be repaid in full.
How Did Dejphon Chansiri Make His Money?
Before football, Chansiri had minimal interest or experience in the industry. His early career involved construction and property ventures in Thailand, including a local taxi service called D Taxis. His father, Kraisorn Chansiri (aged 84), is the chairman of Thai Union Group, while his older brother, Thiraphong Chansiri, serves as the company president.
What Happened to Dejphon Chansiri and Sheffield Wednesday?
In January 2015, a consortium led by Chansiri acquired a 100% stake in Sheffield Wednesday from Milan Mandarić for £37.5 million. The stated goal was promotion to the Premier League by 2017. Initially, there were signs of ambition. Under his leadership, the club reached the Championship play-offs for consecutive seasons, narrowly losing to Hull City in 2016. The club broke its transfer record twice, including an £8 million fee for striker Jordan Rhodes.
But the financial foundations were shaky. Chansiri operated without a board of directors as the sole shareholder. Reports indicate he allegedly sold the club’s stadium, Hillsborough, to himself for a £38 million profit, artificially boosting the club’s pre-tax profit. By 2025, the situation had deteriorated badly.
Why Did Dejphon Chansiri Put Sheffield Wednesday into Administration?
The final months were chaotic. The club faced late wage payments for the fifth time in seven months by October 2025. On 4 October 2025, fans entered the pitch during a 5–0 loss to Coventry City to protest Chansiri’s ownership. The Sheffield Wednesday Supporters Trust led a boycott of merchandise and food sales. The tipping point came on 24 October 2025, when Sheffield Wednesday was officially placed into administration, resulting in an automatic 12-point deduction.
The administration effectively ended Chansiri’s 10-year ownership. On the same day, seat names spelling his name in the North Stand were removed. On 1 December 2025, Chansiri was prohibited from being an owner or director of any EFL club for three years.
What Did Dejphon Chansiri Say in His Statement?
As of the latest reports, Chansiri has not issued a detailed public statement explaining his actions or future plans. The Guardian, reporting on the administration, described the event as a culmination of years of financial mismanagement. The lack of a clear statement from Chansiri has left many questions unanswered.

What Is the Deeper Context Behind Chansiri’s Business Background and Ownership Decline?
The story of Dejphon Chansiri’s ownership is not simply one of a rich businessman losing interest. It reveals a pattern of financial decisions that, according to the Sheffield Wednesday Supporters Trust, were unsustainable from the start. Their investigation into his Thai company network shows that many of his businesses were small, loss-making, or dormant. The combined profits from these entities fell far short of what was needed to cover the club’s losses.
Key incidents during his tenure included transfer embargoes imposed by the EFL for financial rule breaches, legal battles with fans, and repeated failure to pay wages on time. The administration in October 2025 means Sheffield Wednesday now faces a points deduction and a potential sale to new owners. Chansiri’s involvement in English football is likely over, and his Thai companies may face increased scrutiny from creditors.
