Former Leeds United and Manchester United striker Alan Smith says the passion of fans is similar.
Smith has drawn comparisons between two of his old clubs.
He said: “You know the passion that both clubs have got and that's why I loved playing for both clubs. Just because they are very, very similar.
“Leeds fans don't like me for saying it, but the characteristics of both clubs are very, very similar in terms of the beliefs, the history of the clubs, the people who are involved in it, the styles.
“The passion of the fans is very, very similar. I think that's why it made my transition quite easy in that first year.
“And you're surrounded by world-class players, which makes it a little bit easier as well."
