A huge banner saying 'Come Home Ronaldo' will be flown over Real Madrid's next La Liga game by a Manchester United supporters' group desperate for the Portugal star to return to Old Trafford.
ristiano Ronaldo left United to join Real back in 2009 for a then world record fee of £80 million and has enjoyed phenomenal success in the Spanish captial, including the Champions League's 'la decima'.
However, recent reports have suggested he has become disenchanted, especially when it comes to Real's transfer policy, following the departures of Angel di Maria and Xabi Alonso.
Louis van Gaal has spoken publicly about Ronaldo, insisting he would love to sign him, and this has given United fans hope that the World Player of the Year could be enticed back to England.
United Reel, a group which includes members from all over the world, has called for donations to help fund the fly-by, which is due to happen at some point during Saturday's game against Villarreal at the Estadio El Madrigal.
In a statement on their official Twitter account, United Reel said: "We are all united by our love for Cristiano both as a player and as a person. We stand united in our views and will not stop until we BRING RONALDO HOME!"
The supporters group hope their banner will attract worldwide attention and be picked up by the cameras of Sky Sports, and other major networks, when the match is screened live on TV.
