#1 Something to prove

Despite all the golden words and paragraphs of praise - Juventus have something to play for, something to show the world. Ronaldo loves to have something to prove. Juventus have to prove they are beyond not quite good enough to win the Champions League, a tournament Cristiano has a tremendous record in.
They have fallen short in the latter stages of the Champions League consistently in recent years, lacking very often the x-factor in crucial games despite having extremely talented players in their squad.
With both club and player working in-sync towards proving they are the best in the business, there is no doubt that Juventus can allow Ronaldo remain at the top of his game for the foreseeable future.
