The rules of clean financial play and the accusations against Manchester City owners that they have "tricked" the European Union (UEFA) into the issue of funding have come back to the fore, amid calls to prevent the Citys from playing in the Champions League.

This time, claims have grown to mobilize and mobilize senior European players - Bayern Munich, Real Madrid and Barcelona - to punish the heavenly team for allegations that the owner of the club, Sheikh Mansour bin Zayed, hid millions of sponsorship funds to circumvent the rules of fair play by deceiving UEFA in funding sources.

Europe's top players hope to join the club to punish Manchester City, Manchester United's vice-president Bob Woodward, "to hit the traditional rival in the place that hurts him," according to the Sun newspaper.

German magazine Der Spiegel reported that millions of sponsorship funds that allowed Guardiola's children to come close to the UEFA rules for playing clean money were not sponsorships but came directly from club owners in Abu Dhabi.

Spanish league officials have been invited to UEFA to re-open a previous investigation into a case that saw a compromise agreed by City City in 2014, mediated by the current International Federation president of the game, former EU Secretary-General Gianni Infantino, provided for a $ 64 million From which he named only 21 players in his squad to participate in the Champions League, but the penalty was later reduced.

"We have requested all the documents published by Fotbol Lakes and Der Spiegel to present them as part of this case ... We have already received some of them and have been sent to lawyers," the British Sun quoted a senior source as saying.

"If these allegations are true, the level of deception and breaking of rules is too great and can not simply be ignored," the source said.

The source expected that UEFA would not let things pass without serious investigation, adding that there are many penalties that can be faced by Man City, including "a fine and prevented from contracting players and exclusion from European tournaments."

UEFA's rules for clean financial play are rules put in place by the European Football Association to prevent professional clubs from spending more than they earn, so as not to get involved in financial problems.
