Manchester United boss Alex Ferguson has launched a scathing attack on anyone who suggests he should leave his post and retire. The Scottish veteran coach will celebrate his 20th year in charge of Manchester United on Monday amid speculations regarding his future. "I enjoy working and I think it is scandalous that some people say I should retire, it is none of their bloody business I think I have every right to work hard," Ferguson told Sky Sports Network on Friday. "Some people in this life don't want to work, I don't think you should decry anyone who wants to work and it disgusts me people think that way and I am going to continue working."
Since he was appointed as the Red Devils manager in 1986, Ferguson proved to be the most successful coach in the history of English football. The 65-year-old struggled in his first seasons with United but managed to claim the first piece of silverware when he won the FA Cup in 1990. He then led United to eight Premiership titles, five FA trophies and a UEFA Champions League glory. The most significant highlight of Ferguson's coaching career is achieving the treble in 1999.
