Cristiano Ronaldo, arguably the biggest star in world football, may prove that one can, in fact, go home again. 

While speaking with Sky Sport Italy (h/t ESPN) ahead of Tuesday's UEFA Champions League clash with Atalanta, Real Madrid manager Zinedine Zidane hinted that the 36-year-old Juventus forward could return to the Spanish giants during the summer transfer window. 

"Maybe," Zidane said of Ronaldo once again playing for the side where he won four Champions League trophies and two La Liga titles. "We know Cristiano, the person he is, and what he did here. But he's a Juventus player... We'll see what happens in the future. I was lucky to coach him. He's really impressive."
