The mutually rewarding relationship between super agent Jorge Mendes and Real Madrid — specifically, its club president Florentino Perez — is beginning to wind down.

Over the past several seasons, the former semi-professional soccer player, DJ and nightclub owner has represented a number of players in the Real Madrid squad: Cristiano Ronaldo, Pepe, Angel di Maria, Fabio Coentrao and Ricardo Carvalho, to name a few; as well as former manager Jose Mourinho.

The relationship between the agent and club has been beneficial to all parties included – both financially and on the pitch. Mendes’ players are some of the richest in the sport and, with the strength of having his clients in their squad, Real Madrid were finally able to win ‘La Decima’ two seasons ago.

However, following the failed transfers of Radamel Falcao last summer and the recent collapsed deal for David de Gea — as well as the player’s subsequent contract renewal at Manchester United — it is now being reported that the super agent has fallen out with Perez and Real Madrid.

Mendes is upset with the club’s arrogance and unwillingness to enter serious talks with United until the dying hours of the most recent transfer window. While a deal was agreed, the Spanish side’s failure to process documentation on time led to the transfer falling apart at the last second. This appears to have been the final straw for Mendes.

Real Madrid tried to lay blame on United for the collapse of the deal. However, Mendes has placed fault squarely on the shoulders of club president Florentino Perez and the Spanish outfit. The super agent has now cast a favorable eye on Manchester United, knowing that the club is willing to spend significant sums of money during future transfer windows as it continually looks re-establish itself both domestically and in Europe.

There is also a belief that, despite saying Cristiano Ronaldo would end his career as a Real Madrid player, Perez is preparing to offload the Portuguese star before his contract expires in June 2018.

Paris Saint-Germain reportedly tabled a £110 million bid for the forward recently, and even though Madrid were unwilling to part with the player at this time, the understanding is that Perez is ready to cash in on the 30-year-old before his skills begin to diminish – thus lowering his value in the transfer market.

This has further infuriated Jorge Mendes and has seen the super agent begin to sever his ties with Perez and Real Madrid.

Although the representative is not expected to completely close the door on the Spanish club, he is expected to do less business with the La Liga giants in the near future.
