There is a core group of players that have been friends for a long time and this was important for us winning the CL. Ronaldo lost many of his best friends in Real Madrid and players that respected him and did everything for him, so he always showcases his support for them. He lost Ozil, which, ironically enough, angered Ramos a lot and he spoke about it. Casillas was attacked and Ronaldo was not very happy with it. This season Ronaldo lost Di Maria and Xabi Alonso, both players who were not his best buddies, the same way Marcelo is (Ronaldo always sides with Marcelo over Coentrao, his countryman), but players who made him a Ballon d'Or winner and a CL champion with Real Madrid.
Ronaldo is not the selfless player who is a die-hard Madridista and he shares the blame for a few things at the club but he has always taken the side of the players who were more loyal to the team, squad, club, and who were the most dedicated. He even stood in the face of his other countryman, Mourinho, when it mattered. I respect both Ronaldo and Sergio Ramos, beyond their good and bad performances. They are special characters and strange personalities, on and off the field but they are very professional and they both very dearly adore the club and its best interest.
There won't be any drama, they know each other very well and respect each other a lot.
