Portsmouth FC chairman Michael Eisner has warned of a looming financial catastrophe in the Championship after the club posted a £4.36m loss for the 2024-25 financial year. While the loss is relatively modest compared to rivals Hull City, who reported a £41.7m loss in December, and Coventry City, who last month posted a £21.6m loss, it follows the same uncomfortable trend. Eisner, 84, the former CEO of Disney, fears English football has become dangerously imbalanced with the wealth of the Premier League masking the problems below. 'There are dark clouds hovering over the English football pyramid and it seems to me there could be a real collapse where only the Premier League survives,' said Eisner. Every single club in the Championship lost money last year. The combined operating loss of the 24 teams for the last full set of published results in 2023-24 was £411m. 'No club can survive for the long-term in this system and if that continues, catastrophe will happen,' said Eisner. 'If the forces that control the pyramid from the top tiers to the bottom tiers do not make football more sustainable and do it quickly, those dark clouds will deliver more soaking red ink beyond what one can imagine.' While Portsmouth almost doubled turnover to £24.5m in their latest set of accounts, that revenue was largely swallowed up in increased squad costs after their promotion to the Championship. As they fight to maintain their spot in the second tier this season, they remain heavily reliant on the Eisner family's backing. They have put £54m into the club since buying it in 2017.
