Europe's governing body are due to implement the system for the 2013-14 season, which will give them the right to ban teams from Champions League or Europa League participation if they continue to spend more than they earn over a rolling three-year period. The likes of Manchester City and Paris Saint-Germain have risen to the top of their respective domestic leagues on the back of the vast wealth of their Middle Eastern owners. Earlier this month City, last season's FA Cup winners, posted a record-breaking £194.9million loss, with wage costs spiralling to £174million - all bankrolled by Sheikh Mansour. Elsewhere, the Court of Arbitration for Sport are set to hear a dispute between UEFA and Swiss club FC Sion, who responded to their exclusion from the Europa League by mounting a civil action. Wenger believes such litigation and the collective power of the top clubs could eventually soften the stance of the European governing body towards how they implement the new financial restrictions. "Will they [UEFA] have the legal power to force it through? I question it," said the Arsenal manager, whose side will look to secure safe passage through to the knockout stages of the Champions League with victory over Borussia Dortmund at Emirates Stadium on Wednesday night. "In other countries, you have as well Paris Saint-Germain, Malaga. Once they represent a force together, it will be difficult to fight against." The Gunners boss continued: "When I see the numbers announced by Manchester City, do you really think it will work in 2013? I cannot see it when the wage bill is bigger than the turnover. Frankly, that cannot happen in one year. "Secondly, with what happened with Sion challenging UEFA, they have lost a lot of power. There is also the statement of [European Club Association chairman Karl-Heinz] Rummenigge against UEFA, representing the hundred clubs who are in there. "We live in a world where any decision made is challenged. "Europe has a little bit created that and we see how far Europe has gone. The authority of the legal affairs is challengeable everywhere."
