UEFA have closed the loophole which enabled Chelsea to spread the cost of their record £600m transfer spending over up to eight years.
Mail Sport reported earlier this year that a number of Chelsea's top-flight rivals had accused the club of attempting to cheat Financial Fair Play regulations by using amortisation to spread the cost of transfer fees - after Mykhailo Mudryk joined for £88m on a eight-and-a-half year deal.
However, UEFA have now confirmed that going forward clubs can can only spread a player's transfer fee across a maximum of five years - even if they are signed to a contract that is longer.
