Cristiano Ronaldo consults with his own diving expert

Over the summer, several Barcelona players (including Sergio Busquets) met with the diving experts at the Miami Seaquarium in an effort to stay one unnecessary tumble ahead of Real Madrid this season.

Now, coming off a disappointing loss to Barca in which nothing seemed to go his way and looking to maintain a three-point lead in the league table, Cristiano Ronaldo is using his winter break to study with his own diving master in an effort to keep up with his rivals.

It's unclear whether this particular dolphin was recommended by Angel Di Maria or if Ronaldo tracked down the master that taught Alexis Sanchez's ultra-intensive crash course, but the message here is clear: it's on.
