Barcelona and Manchester United were among the clubs punished by Uefa on Friday for breaking financial fair play (FFP) rules during the 2022/23 season.
United were slapped with a €300 000 fine for failing to meet the break-even requirement that tries to limit the losses made by clubs.
Spanish title holders Barcelona were given a 500 000 euro penalty for including profits from sales of intangible assets, which are not relevant income under the rules, to balance their accounts.
FFP rules, which were brought in in 2010, have allowed clubs to report losses of no more than €30 million over a three-year period.
Last season was the last year those rules will be used by Uefa before new licensing and sustainability rules are phased in over the next three seasons.
Champions League finalists Inter Milan, AC Milan, Paris Saint-Germain, Monaco, Roma and Marseille avoided sanction after meeting targets set by a Uefa settlement agreement.
Belgian club Royal Antwerp and Turkish side Trabzonspor were given the biggest fines of two million euros each.
