Arsenal manager Arsene Wenger has admitted that the current Financial Fair Play regulations confuse him, according to Sky Sports.
Despite holding a degree in economics the Frenchman believes there is no clear indication as to how clubs are sanctioned.
European powerhouses Manchester City and Paris Saint Germain have been handed extraordinary fines by UEFA in recent years, after investing heavy sums in player transfers.
City were order to pay £48 million to UEFA, but despite this they still splashed out £28 million on Wilfried Bony from Swansea in January, meaning they once again had the biggest transfer outlay of any Premier League club.
And because of Bony's arrival, Stevan Jovetic, a £22 million signing from Fiorentina in 2013, was cut from the Champions League squad in order to make way for the Ivorian.

Incidents such as these are becoming more commonplace, and for years Wenger - who studied Politics and Economics at the University of Strasbourg - has supported moves to control the spending of clubs by UEFA. However, he admits he doesn't understand what the current guidelines have set out.
"It depends what you call Financial Fair Play as that notion has changed," said Wenger.
"Is it just your income created by the gates? Is it the gates and commercial? Is it only the gates and the television? Is it naming rights as well?
"It is not clear to people what Financial Fair Play means, the rules are very complicated."

Wenger worked under tight transfer policies to pay for the Emirates Stadium move, and because of that prudence the north London side can now reap the rewards, with the signings of Alexis Sanchez and Mesut Ozil costing £35 million and £42.5 million respectively.
Wenger said: "The Financial Fair Play rules have to be respected by everybody and if one club respected always the Financial Fair Play, and you can underline always, it is Arsenal, then we do not have to talk about that."

Wenger was speaking ahead of the visit of Leicester City on Tuesday night. The Gunners have received a big boost for the game with the news that striker Alexis Sanchez has recovered from a hamstring injury.
Jack Wilshere and Alex Oxlade-Chamberlain are still injured whilst Leicester defender Robert Huth could make his Foxes debut after suspension. Wenger will want to see a response from his players after defeat in the north London derby to Tottenham on Saturday.
