#7 Cristiano Ronaldo - Manchester United to Real Madrid

The story of how Manchester United came to sign Cristiano Ronaldo is pretty much part of footballing folklore now - with Sporting Clube de Portugal looking at the €19 million with plenty of regret now. A stellar 6 years at Old Trafford followed, with Ronaldo reaching some atmospheric levels.
He left with a final gift - a world record fee for Manchester United to rebuild with - and Sir Alex Ferguson used it well. However, given the heights Ronaldo went on to reach with Real Madrid, most Red Devils would rather have the player than the money.
€94 million is a huge, huge amount - but Real Madrid would not have it any other way. Even if Cristiano Ronaldo is experiencing a decline, the success he has brought to Los Blancos has well and truly justified his fee.
