(CNN) -- Michel Platini, the president of the governing body for European football (UEFA), has hit out at the large fee offered by Real Madrid for the Portugal playmaker Cristiano Ronaldo.
Platini, the boss of European football's governing body, has crticized Ronaldo's proposed transfer
English Premier League side Manchester United announced on June 11 that they had accepted a world record transfer fee of $130M for the 24-year-old from the Spanish side.
The news came in the same week that Real confirmed their capture of Brazil forward Kaka for $92M from Italian side AC Milan.
The news has prompted Platini, who's vowed to clean up the finances of football to create greater parity among sides, to criticize the move.
"These transfers are a serious challenge to the idea of fair play and the concept of financial balance in our competitions."
"UEFA is working hard with clubs to set up a new set of rules as soon as possible to clean up the system and give it a more solid, transparent base," he added.
The new arrivals to the Santiago Bernabeu stadium, Madrid's home ground, are key elements in the strategy of new president Florentino Perez, who has pledged to bring success back to the club by signing the world's top footballers whatever the cost.
Perez's policy is a repeat of his actions in his first stint in charge between 2000-06. In what became known as the "Galacticos era", Perez signed a number of multi-million dollar superstars that included Luis Figo, David Beckham and Zinedine Zidane.
The free-spending policy brought the club great success commercially, most notably through Beckham's high-profile, as it exploited the marketing potential of its brand globally. The former Manchester United midfielder's popularity unlocked lucrative markets across Asia in particular, bringing in millions of dollars from shirt sales and other merchandise.
Despite the depressed economic climate, the re-elected Perez has embarked on an eye-watering spending spree to reverse this apparent recent decline of the side who have ceded domestic supremacy to arch-rivals Barcelona.
"What the world considers to be an exorbitant cost, he (Perez) considers as the only way for Real Madrid to survive," Luis Nieto, deputy editor of Spain's AS Sports Newspaper, told CNN.

Privately-owned by its 93,000 members, Real Madrid are one of the richest clubs in the world with an estimated annual turnover of more than $450 million. In addition to the revenue from ticket sales and lucrative sponsorship deals, Real are tied into a ground-breaking television contract with Spanish broadcast company Mediapro worth around $210 million a season.
Crucially, they enjoy considerable support from Spanish banks. Unlike rivals such as Manchester United, who are part-financed by hedge fund companies and international banks demanding high rates of interest, Real do not face the same pressures, such is their influence in Spain.
"The money comes from what's in the bank, plus the loans the club gets, plus the income from the players that he (Perez) will sell to other teams," added Nieto.
In 2001, Perez -- a property magnate -- masterminded the sale of their training ground in central Madrid for a staggering $478 million. The sale helped clear the club's massive debts at the time and paved the way for the purchase of players such as Figo and Zidane. The site is now home to four skyscrapers that dominate the city's skyline.
With the arrival of Ronaldo, the Perez policy of "speculating to accumulate" will swell the club's coffers by $75 million a season, according to research commissioned by Weber Shandwick Sport with one of the world's leading sport business experts.
"Ronaldo can be viewed in the same bracket as Beckham when it comes to global commercial impact, if their image is controlled right and Real Madrid improve their results in the UEFA Champions League as a result of their arrival," said Professor Simon Chadwick, Director of the Center for the International Business of Sport (CIBS) at Coventry University in England.
He added: "Becks sold a million shirts in his first six months at Real Madrid when he was just one of several 'Galacticos' turning out for the all-whites, alongside the likes of Zidane, Raul and the Brazilian striker Ronaldo amongst others.
"Even if Real signed one or two of the other stars, there would be a real focus on Cristiano Ronaldo's and Kaka talents on the pitch, but also their brand off it. That will pay for their transfers several times over, even with a bumper salary package."
