Chelsea, Barcelona and Aston Villa were among several clubs fined by Uefa on Friday for breaching European football's financial sustainability requirements.
Uefa said the clubs had not complied with its football earnings rule. Chelsea and Villa were also penalised for breaching the squad cost rule.
Chelsea were ordered to pay a fine of €31 million for the two breaches.
They could have to pay an additional €60 million if they fail to comply by the end of a four-year period as part of a settlement agreement.
The Blues have spent the most money of any club in Europe since a consortium led by US businessman Todd Boehly bought the Premier League giants in 2022.
Barcelona incurred a fine of €15 million, with a further €45 million conditional on a two-year settlement agreement.
Villa must pay €11 million and risk a further fine of €15 million if they breach the terms of their three-year deal.
French club Lyon have agreed to be excluded from European competition if their relegation to Ligue 2 on financial grounds is confirmed.
They were also fined €12.5 million.
