The Boston Celtics, fresh off their 2024 NBA championship victory, face long-term financial challenges due to a ballooning payroll and impending losses from supermax contracts. Owner Wyc Grousbeck announced the team's sale for estate planning reasons, amidst reports of a rift with his father over financial management. Meanwhile, Manchester City is embroiled in a major legal battle as the Premier League investigates 115 charges of financial misconduct dating back to 2009-2018, potentially risking severe penalties, including league expulsion. The trial, referred to as the 'sports trial of the century', began recently and could last up to ten weeks, with City maintaining their innocence. City's financial dealings have been scrutinized since their acquisition by Abu Dhabi's ruling family, and they previously overturned a UEFA ban in 2020. The outcomes of both situations could significantly alter the landscape of professional basketball in Boston and football in England.
