This summer the Premier League is replacing its profitability and sustainability rules with a new financial framework centred on the squad‑cost ratio (SCR) and sustainability and systemic resilience (SSR). The SCR caps total spending on player wages, transfer amortisation and agent fees as a percentage of revenue, while £70m in annual stadium infrastructure costs for Manchester United are excluded.

Sir Jim Ratcliffe wants a new 100,000-seater stadium for Manchester United to generate extra revenue and fund a stronger squad. The £2bn project would be built off‑site and could shift the club away from Old Trafford, solving capacity and security issues while boosting matchday and corporate income. The overhang and canopy will be costly, but the increased capacity should raise matchday takings and attract more sponsors.

Newcastle, with only £52m in matchday income, faces a tougher challenge. Their fans, like Charlotte Robson, worry that moving from St James' Park would damage identity, yet a new stadium could raise yields per supporter and diversify revenue beyond matchday sales.

Experts caution that commercial gains depend on location and fan acceptance, making the financial case for a new stadium uncertain despite the potential upside.
