Real Madrid president Florentino Perez’s fury at Zinedine Zidane’s shocking league campaign last season is revealed in a new fly-on-the-wall documentary of La Liga set to be released in the UK.

With ten games left of the season and Real Madrid 15 points off the pace Perez tells Eibar president Amaia Gorostiza in pre-match hospitality: ‘Aside from the game on Tuesday (an away win against PSG in the Champions League) it has been a horrible season, horrible.’

He is then shown suffering in the directors box and describing the performance as awful as Madrid make hard work of narrowly beating Eibar 2-1 thanks to a late Cristiano Ronaldo winner.

The footage, shown for the first time in Amazon Prime Video’s ‘Six Dreams’ documentary series supports the widely held theory that Zidane would have been sacked but for his success in the Champions League.

Despite beating Liverpool in Kiev in the Champions League final the club still made plans for this season without consulting the French coach, leading to his resignation at the end of May.

The series of six episodes from inside the dressing rooms of six La Liga clubs also lifts the lid on the inner turmoil at Sevilla as coach Eduardo Berizzo is sacked while still recovering from cancer surgery.

After Berizzo’s diagnosis with prostate cancer is made public, and before his operation, he holds a press conference at Sevilla to thank all those who have wished him well.

The ‘Six Dreams’ cameras capture a poignant moment between the coach and the club’s long-serving press officer Jesus Gomez when, walking away from the conference, Berizzo tells Gomez: ‘I just wanted to thank everyone. I have even had a message of support from Vicente Del Bosque.’

Gomez responds: ‘There has been an amazing reaction.’ And Berizzo tells him: ‘It’s like my mother says: "For people to love you you have to die first!"’

Berizzo returned to work just 17 days after his operation and then made a 1,300 miles road trip from Sevilla to San Sebastian, because he was not allowed to fly, to be in the dug-out to watch his team play Real Sociedad.

They lost 3-1 and despite still being fifth in the league and in the next round of the Champions League where they were due to face Manchester United, he was sacked before Christmas. ‘Football is like that,’ said the club’s president Jose Castro Carmona.

Six Dreams goes behind the scenes at clubs beyond the big two as part of LaLiga’s strategy to present the entire breadth of the league.

As well as Berizzo and Eibar president Gorostiza, Betis’ Mexican midfielder Andres Guardado, Girona Sporting Director Quique Carcel, Atletico Madrid midfielder Saul Niguez and Athletic Bilbao forward Inaki Williams are also followed through the ups and downs of last season.

Athletic Bilbao's first high-profile black player Williams, who was born in Bilbao to Liberian parents, reveals how he still has to fight against racist attitudes.

‘I want to open people’s minds,’ he tells a group of young players. ‘This thing that people have in their heads that a black player cannot play for Athletic Bilbao or this black man is not Basque.

‘You can still hear nowadays people say: “How can this black man play for Athletic?” No, no. I’m black but I’m also Basque, I was born here. I feel Basque and I want to open the doors for all the people who fight and apply themselves every day to be able to play for Athletic.’

Previously unseen footage also lays bare the emotion of Fernando Torres's last ever home league game for Atletico Madrid and its affect on his close friend Saul.

The Spain midfielder was just a young kid at the club when Torres was in his first spell. He can be seen crying as Torres takes the microphone on his last day to address the supporters. ‘It’s hard to think when I come back next season he will not be there,’ he says.

Sadly one man largely absent from the six episodes is Diego Simone although he can be heard shouting at his players from behind a closed dressing room door at the Camp Nou before his team’s meeting with Barcelona.

'We have to belief in the spirit of the whole team! There are 12 games left guys. Twelve finals! It doesn’t matter who we are up against! We are all the same! We are all the same,’ he roars, before emerging dressed in the customary black suit and coat and striding past the camera in the bowels of the Camp Nou.
