Surprising take from Marcelo! In a recent interview, the legendary Real Madrid left-back revealed that, despite facing the likes of Messi and Jesus Navas, his toughest opponent was actually his own teammate—Cristiano Ronaldo. Marcelo talked about their fierce training battles and even a heated Brazil-Portugal clash before CR7 joined Los Blancos. Iron sharpens iron, and these two certainly pushed each other to greatness. Thoughts, Madridistas? #Sports #Soccer #RealMadrid
