What makes the situation around these two clubs particularly intriguing is that they did engage in a controversial swap deal last summer. Omari Kellyman moved from Villa to Chelsea for £19m ($25.5m), while Ian Maatsen moved the other way for £37.5m ($50m).
Both figures raised eyebrows, particularly when you consider that Villa could simply have paid £18.5m for Maatsen and sent Kellyman across as part of the deal. The fact that both sides received payments for a home-grown player indicated a desire for PSR gains. It seems UEFA have picked up on this, as The Times' report states that European football's governing boy has confirmed they "knocked back the value of at least one deal involving both Chelsea and Villa".
