( CNN ) -- Perhaps somebody forgot to tell Rafael Benitez that the Oscars were last week . It does n't matter . Benitez 's extraordinary post-match performance Wednesday managed to combine the good , the bad and the ugly as the Chelsea manager launched a scathing attack on his employers and club 's supporters before revealing he will quit at the end of this season . Here was Benitez , the victim . Here was the man in the middle of one of football 's most high-pressure jobs being circled by an army of critics . Perhaps the adrenaline kicked in . Perhaps he had just had enough . It was fight or flight . Now he will await his fate , with the English club 's billionaire owner Roman Abramovich -- who has employed nine managers in 10 years -- expected to take note . Foreign owners in UK football : The good the bad and the ugly . Since Benitez walked into Stamford Bridge last November , the former Liverpool boss has been a sitting duck . Protests , placards , songs about former managers from the stands -- even the most genial of men would have found their patience challenged . Replacing a Chelsea favorite and Champions League-winning manager in Roberto Di Matteo was never going to be easy , but for Benitez , it has been a losing battle . Out of the Champions League , beaten in the country 's third cup competition by Swansea and 19 points off the league leader , Chelsea 's season is in danger of collapsing . Contrast that with the fact that the Blues were third and four points behind then leader Manchester City when Di Matteo was given his marching orders . The Europa League is not seen as salvation -- not at least by those who sit in the stands with their thumbs pointed downwards in Benitez 's direction . More woe for Chelsea boss Benitez . Then there 's the speculation surrounding alleged disagreements with key players and the constant scrutiny of his side 's failings , and it 's easy to see why Benitez has found life in west London so difficult . Not even Wednesday 's 2-0 win over second division Middlesbrough in the FA Cup -- which earned a quarterfinal clash with Manchester United -- could please the traveling Chelsea fans , who once again voiced their displeasure at the man they call the `` interim manager . '' `` I have been in charge in football for 26 years , '' he told reporters . `` 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 . `` A group of fans , they are not doing any favors for the team when they are singing and wasting time preparing banners . '' Benitez takes over Chelsea . While Benitez accepted the post until the end of the season , he hit out at the use of the term `` interim manager '' and the club 's insistence on using the title . `` It 's because someone made a mistake , '' he added . `` They put my title `` interim manager '' and I will leave at the end of the season , so they ( the fans ) do n't need to waste time with me . `` They have to concentrate on supporting the team , that 's what they have to do . In the end , they are not doing any favors 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 can not 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 . `` I am the manager . I will manage the players and I will make decisions . I will leave anyway -- I 'm interim , as they say -- so they 're wasting their time . '' How much longer Benitez will have on screen in his current role is up for debate , but this is one performance his critics wo n't forget .
