Watch: Ronaldo scores 6 minutes into season debut

Well, that didn't take very long.

Real Madrid star Cristiano Ronaldo, battling a knee injury that ended his Euro 2016 campaign in the final, returned to action against Osasuna on Saturday and quickly shed doubts of his fitness, scoring six minutes into the match with an easy tap-in.

Gareth Bale set up the goal with a short pass across the face of goal but looked a touch offside in the build-up to the play. Still, It's unlikely that either Ronaldo or Real Madrid will care.
