Sir Alex Ferguson: "It will be interesting to see the kind of reaction he gets.
"There are very few players who have played for both clubs.
"Paul Ince obviously got a bad reaction from our fans when he went to Liverpool, and Michael might get that on Sunday.
"But he is experienced - that is important. Everyone likes to be liked but I don't think it will bother him.
"His record at Liverpool stands him apart from even the likes of Paul when he was with us.
"The goals he scored for Liverpool mark him down as one of their best-ever strikers.
"That stands him in good stead in terms of the Liverpool fans - but it is difficult to say."
