According to The Guardian.
England Premier Soccer League
Clubs spent almost £250 million on player transfers in just four days at the end of June, a figure that exceeds the total spent in the entire January transfer window. The Premier League will now investigate teams' player sales and purchases for compliance with the Profitability and Sustainability Rule (PSR).
Six clubs - Aston Villa, Chelsea, Leicester City, Newcastle, Everton and Nottingham Forest - that could be at risk of exceeding the PSR's £105m loss cap over three years, have been particularly active in the run-up to the unofficial June 30 "transfer deadline".
The English media has pointed out that several high-profile deals have been made between these clubs, such as the swap of youth players between Everton and Villa, as well as a player deal between Chelsea and Villa. Although these deals did not break the rules, they were seen as taking advantage of the
PSR rules
of vulnerability.
The Premier League has warned clubs that any transfer deal over £1 million could be subject to scrutiny to prevent clubs artificially inflating transfer fees.
Soccer finance expert Kieran Maguire points out that determining a player's fair market value is very difficult because every player is unique.
Although the PSR rule is expected to be replaced by the new player spending cap rule next year, Maguire believes there could still be room for similar maneuvering under the new rule. The article also mentions the player swap deal between Barcelona and Juventus in June 2020, suggesting that the practice could become more common in the future.
