Manchester United title winner Dimitar Berbatov says it's the right move for Cristiano Ronaldo to take the No7 shirt.
New signing Ronaldo has taken his beloved No.7 off of team-mate Edinson Cavani – who now has the No.21.
Berbatov told Betfair: “Are you superstitious? The same goes for football players.
“The number plays a big, big role in a football player's life. In the case of Ronaldo, he is very attached to No.7.
"That number brought him great success over the last 12 years.
“Even if he wasn't No.7 he would be the same player because the number doesn't play, but sometimes we are like this as football players.
"You want that specific number. I always wanted No.9 when I was playing, especially at Tottenham.
"And I would also wear No.10 when I was playing Champions League football. It is important.
“It looks silly sometimes. Players can fight over numbers. One says: 'I want that number' and the other says: 'no it is already mine I am not giving it up to you'. You fight.
“But for some players it really matters."
