#3 Cristiano Ronaldo (Juventus)

After historically winning 3 consecutive UEFA Champions League trophies, Cristiano Ronaldo decided to trade in the Madrid Whites for Juventus' stripes in the hunt for a new challenge.
If the start to his Serie A career is something to go by, he certainly has been challenged, scoring just two goals - both of which came yesterday against Sassuolo - in 4 appearances for Juventus.
However, his reputation of coming alive in the UEFA Champions League simply disallows you from leaving him off this list regardless of form. Ronaldo is, quite simply put, a different animal altogether when it comes to Europe's biggest stage.
He has scored 10+ goals in each of the last 7 editions of the tournament, with a total of 105 goals and 27 assists from just 101 appearances with Madrid, helping Los Blancos win the title 4 times along the way.
There would be no better time and place for his Juventus career to take off than in the Champions League and he definitely will be expected to bring his A game in the tournament.
