"Keep that fire on! Your best is still to come!" — this is a message global football star Cristiano Ronaldo sent to Khvicha Kvaratskhelia via Instagram.

"The toughest battles in football are often the ones nobody sees.

I know that feeling, Kvara. But never forget what brought you this far, and don't let a difficult moment make you doubt how far you can go. Keep that fire on. Your best is still to come!" Ronaldo wrote on Instagram.

Khvicha Kvaratskhelia—the captain of the Georgian national team and a star for PSG—addressed the injury he sustained against Barcelona in the Champions League via Instagram, writing: "I must return even stronger for my people, who are always by my side."
