6) Cristiano Ronaldo
Three-time Ballon d’Or winner Cristiano Ronaldo was very close to joining the Scousers in the same season when he joined Manchester United. The Portuguese star did state that Liverpool was his preferred move and not United in 2003, showing how close the Reds were to signing arguably one of the greatest players of all time.
Then Liverpool boss Gerard Houllier admitted that he turned down the chance of signing the forward and the fans are left wondering what kind of impact Ronaldo could have had for the team.
The Madeira born forward found the back of the net 84 times in 196 appearances for Manchester United, winning three Premier League trophies, one FA Cup and a Champions League title.
At the time of him leaving Sporting CP, a teenaged Ronaldo said: "Liverpool are one of the best clubs in England and it would be a dream for any player to represent a club of such traditions.” He added: "I will have to hope they make an offer that is good for both Sporting and myself.”
The Madrid forward further said: "The English league is not one of my favourites, but it is very interesting. I think my way of playing can be reconciled in the Premiership. If a player has quality, then he can play anywhere.”
