Nastasic has revealed how Manchester United skipper Vidic gives him advice about settling in to life in England.
City's Mr Nasty said: "When I arrived I asked him for advice. For me he is a great friend and a great person.
"He gave me advice about lifestyle and adapting to English football. But he never told me I joined the wrong club.
"Mind you, I never looked at the other side of Manchester.
"The first two games gave me confidence because I noticed that I could cope with the Premier League. I expected a transition of six months."
