MADRID - Two games without a goal is run of the mill for most soccer players, but for Cristiano Ronaldo it constitutes a drought.

Ronaldo will be looking to forget his early-season struggles as Real Madrid aims to lay down a marker in its quest for a third consecutive Champions League at Borussia Dortmund on Tuesday.

The Portuguese remains the strong favorite to match Lionel Messi's record of five Ballon d'Or wins for his starring role in guiding Madrid to a first La Liga and Champions League double in 59 years.
