Former Manchester United striker Frank Stapleton has backed the club's decision to accept a world record £80 million bid from Real Madrid for Cristiano Ronaldo.

Stapleton told Sky Sports News: "I feel that money will be used very, very quickly.

"When the top players have left Manchester United the actual team has not been diminished in any way, they have gone on to be stronger again.

"The Champions League final for Sir Alex Ferguson will have opened his eyes, what Man United need to do to stay top, not only in England but in Europe."
