Carlo Ancelotti explains how Gareth Bale and his agent went behind his back to complain Real president Florentino Perez

Carlo Ancelotti was sacked at Real Madrid in 2015, a year later after he helped them win the La Decima.

Real Madrid superstar Gareth Bale has been slammed by his former manager Carlo Ancelotti after the Italian boss revealed that the Welsh international went behind his back and complained to the La Liga outfit's president Florentino Perez during his time at the club.

The ex-Chelsea and Paris Saint-Germain manager helped Real win the La Decima after defeating Atletico Madrid in the Champions League final in May 2014. A year later, Ancelotti was sacked from his post after the end of the 2014/15 season and in January 2015, Bale's agent Jonathan Barnett complained to Perez that Bale was unhappy with his playing position.

Bale's preferred position is in the middle, while his former boss played him out on the wide. What disappointed Ancelotti is that the Italian being informed of the player's situation by Real president rather than the former Tottenham Hotspur star approaching him directly.

"One morning in March I received a phone call from the Madrid general director saying that the president wanted to speak with me at the end of training that day. This was very unusual. When I visited the president, he told me that Bale's agent had been to his office to speak about the 'Bale situation'," Ancelotti explained, as quoted by FourFourTwo.

"In January, Bale's agent had been saying things and perhaps felt his position was strong because he had already spoken with the president. Now he was telling the president that Bale was unhappy in his position. He wanted to play more centrally.

"The president asked me what we were going to do and I told him 'Nothing'. It was impossible to change his position at that stage of the season because I would have had to change the whole system and move many more players around. I also told the president that I was surprised the player could not speak directly with me. That would be normal. I would have expected the player to come to see me.

"Bale had fantastic world-class qualities and all that I was trying to do was help him understand his core strengths so he could fulfil his potential and by the way, that I was more qualified than his agent or the president to help him with that.

"I told the president that I would speak with Bale myself the next day, which I did after training. I told him 'I know that your agent spoke to the president. Why didn't you come to speak with me about what you want?'. He said 'Yes, OK, no problem.'

"I explained to him what I had said to the president, how it was impossible for me to change the system as it wasn't just one position, it was the whole team. I was clear with him. I told him that we could try some things in the summer, next year's pre-season, to change his position, but not now."

Ancelotti, who was without a job this season will manage Bayern Munich from the 2016/17 season.
