Real Madrid legend Hugo Sanchez has questioned the club's decision to sell Angel Di Maria to Manchester United in the summer.
Di Maria moved to Old Trafford in a British record £59.7 million deal in what was widely believed to be a transfer instigated by Real Madrid president Florentino Perez.
Xabi Alonso was also allowed to leave, joining Bayern Munich, but the former striker believes it is the Argentinian who will prove irreplaceable for Carlo Ancelotti.
Sanchez is of the opinion that Real Madrid had to sell to balance to books. However, he also believes that Ancelotti had little say in Di Maria's future.
Difficult to spend
He told AS: "It's hard to tell from the outside. It's very different whether you're a coach or a director.
"It's very difficult to spend, spend, spend and not receive anything. If you spend you will have to sell. In this game of mathematics it all depends on the directors.
"I imagine that as a coach, Carlo Ancelotti would have liked Di Maria and Alonso. But mostly Di Maria, as there are many players who can replace Alonso.
World's best player
Despite Manchester United's struggles under Louis van Gaal, Di Maria has hit the ground running at Old Trafford. The 26-year-old has scored two goals thus far and has looked capable of paying back to huge transfer fee.
Sanchez also believes Di Maria will prove good value for money, saying the midfielder remains one of the top players in the world. he also reiterated his bafflement at Perez's decision to sell him.
"Di Maria was one of the best players in the world and helped Madrid a lot, but the accounts had to be done," he continued.
"I don't know why Di Maria left. He's one of the best players in the world."
Balancing the books
Real Madrid have been renowned for their appetite in the transfer window. They have held the transfer record continuously for 14 years, breaking it five times in the process.
Most recently, the club signed Gareth Bale for a reported £86 million, forcing the club to part ways with Mesut Ozil. After signing James Rodriguez for a comparably tame £63 million, Di Maria was also allowed to leave for the Premier League.
The case of Real Madrid's transfer activity is an excellent advert for Uefa's Financial Fair Play system, which has stopped Los Blancos from using their financial supremacy to stockpile the world's best talent.
