Rafa Benitez faces the sack today after accusing Chelsea owner Roman Abramovich of undermining him in a sensational rant last night.
The Chelsea interim boss vowed to leave his post at the end of the season and also launched a scathing attack on the Chelsea supporters who have plagued his reign with chants and banners against him.
And in an amazing outburst Benitez turned his fury on the Chelsea owner saying he did not know he was being given the title "interim manager" when he accepted the job, and admitted it had undermined his tenure saying: "It was a massive mistake."
Senior Chelsea officials last night described Benitez as having "gone mad."
One added: "They call it Loco in Spain don't they?"Ranting Rafa unleashed a devastating fight-back saying he'd been shown a lack of respect since becoming Chelsea boss despite 26 years in football and winning nine trophies as a club manager."
Benitez' outburst could trigger Abramovich to act swiftly and get rid of his manager before the end of the season despite setting up an FA Cup quarter final against Manchester United after a 2-0 win over Middlesbrough last night.They could turn to former boss Avram Grant as another "interim" appointment until the end of the season.
The Spaniard let rip for 13 minutes in his post hardly breaking flow as he accused a section of Blues fans of undermining the players efforts to qualify for the Champions' League next season.
But Benitez said: "A group of fans, they are not doing any favours for the team when they are signing and wasting time preparing banners.
"It's because someone made a mistake. The put my title 'interim manager', and I will leave at the end of the season, so they don't need to waste time with me.
"Why put interim in the title? Why did they need do that? Maybe they thought: "He was at Liverpool", so put interim in".
"I have been in charge in football for 26 years. I have won the Champions League, won the FIFA Club World Cup, the FA Cup, the Italian Super Cup, the Spanish league twice, nine trophies, all the trophies you can win at club level.
"The fans have to concentrate on supporting the team, that's what they have to do.
"In the end, they are not doing any favours to the club, to the rest of the fans and to the players.
"Every game they continue singing and they continue preparing banners, they are wasting time. What they have to do is support the team.
"If we cannot achieve what we expect to achieve, that is to be in the top four and be in the Champions League for next year, I will leave; they will stay in the Europa League.
"They have to take responsibility too. If they put players under pressure, they don't create a good atmosphere at Stamford Bridge, they have to realise they are making a big mistake because the rest of the fans would like to see the team in the Champions League next year.
"I'm the manager and I will be managing the team. I like to manage players and not names, so I will pick my team, and I will make decisions and at the end of the season, I will leave anyway because I am interim like they said.
