Maybe going back is to suffer a little.“But after I arrived, he came in again. He came back to visit the people he worked with for so many years. And he travelled with us once again."And that’s what I said to him, ‘It doesn’t make sense that we’re playing in London and go on a private train and you, Sir Alex, will go by car. You’re not going by car. No. Go by train, with the team’.“But he is so respectful that he becomes even a little shy in this approach. We have to make him feel loved.“In our head there are no ghosts, no complexes, no such thing.”Since his arrival as Van Gaal's replacement last summer, boss Mourinho has admitted he has been gently coaxing Ferguson back into the centre of things at United.Ferguson, 75, has started travelling with the team for European games again this season, flying in the official party on the team plane and staying in their hotel.
