Sir Alex Ferguson could not resist taking a dig at new Chelsea boss Rafa Benitez

Manchester United boss Sir Alex Ferguson has already taken a swipe at Rafa Benitez after he took charge of Chelsea.

Priority

Benitez, meanwhile, vowed to win over Chelsea fans after the news of his appointment was met with a hostile reaction from some of the Stamford Bridge faithful. "My priority was to work in the Premier League, I'm really happy to be here with a top side," Benitez said on Thursday evening, with Sunday's clash with Manchester City already on the horizon. "For me the most important thing is I am here because I want to be here. I was looking for the right opportunity, I was looking for a top side who can fight for trophies."I don't care about the short-term (deal), what I have in my head is to win every game. We have five trophies to fight for. We will see what happens, in seven months we can win some trophies. "At this level you are expected to win, do it well, and win trophies. I have a lot of years' experience at this level, and I will do what I have to do to win games. "I like to do things in the right way for the fans. I am sure they will be happy with a manager with a winning mentality."
