Chelsea and Aston Villa have been fined by UEFA for breaching its financial rules; Chelsea have to pay £27m and could pay up to £52m more if they do not stick to the settlement agreed; Villa have to pay £9.

UEFA defines 'transfer balance' as the difference between cost savings from outgoing players and the new costs from incoming players at the time of the club’s List A submission. In simple terms, any spending to add players to Villa's UEFA List A squad must be offset by the income generated from player departures.
