Larsson told Aftonbladet: “Alex Ferguson called me last night, and welcomed me to the club.”
“We discussed last night’s match, and he wanted me to come to Manchester to train.”
Larsson will join Manchester United on loan from January 1st to March 12th.
He added: “I am going over there to play as much as possible, but I have no idea of how SAF will be using me. We`ll see how much playing time I will get. Back up? Yes, to start with. And then we will see what I can do to contribute and how things will end up.”
Helsingborg chairman Stig-Inge Fredin will not interested in extending the loan deal, if Manchester United asks.
