It is the 10th time United have been top of the league, compiled by Deloitte for the highest revenue generating club in the world, although the winning margin has never been smaller.
United’s Europa League victory was crucial to their financial performance, with Real Madrid’s figures boosted by winning the Champions League and their Spanish league triumph.
The list only looks at revenues accrued and does not take into account club debts.
This year’s battle for first place was the closest ever, with revenue in 2016-17 of €676 million— just €1.7 million ahead of the Spanish giants.
United on Monday confirmed the signing of Chile striker Alexis Sanchez from Arsenal in a deal which is expected to make him the Premier League’s highest-paid player of all time.
Barcelona — one of Sanchez’s former clubs — are third in the 21st edition of the list compiled by the British-based business advisory firm, followed by Bayern Munich, Manchester City and Arsenal.
A separate study released earlier this month showed Premier League leaders Manchester City have greater financial muscle than any other club in world football, with Arsenal second and United in seventh place.
