Video: Real Madrid stars Cristiano Ronaldo, Marcelo show off secret handshake

Real Madrid star Cristiano Ronaldo appears to have a good friendship with teammate Marcelo as the pair recently showed off a secret handshake.

During a training session prior to the side's 2-1 victory over Athletic Bilbao on Wednesday, the group looked in good spirits.

It is not a surprise that the players are feeling positive as prior to Wednesday's La Liga match, the Spanish giants had not conceded a goal in the top flight.

This Saturday, Rafael Benitez's team will take on Malaga at the Bernabeu.
