Dejphon Chansiri is a Thai businessman who is the current owner of English Football League Championship club Sheffield Wednesday.
Chansiri's family controls the Thai Union Group, the world's largest producer of canned tuna. In January 2015, a consortium led by Chansiri acquired a 100% stake in Sheffield Wednesday from Milan Mandaric for £37.5m and targeted promotion to the Premier League by 2017.
During the summer of 2015, Chansiri changed many aspects of the Sheffield Wednesday set-up including the backroom staff and players, such as sacking manager Stuart Gray and replacing him with Carlos Carvalhal, who had previously managed Turkish side Besiktas and several clubs in his home country of Portugal.
