Former Manchester United and Real Madrid star Ronaldo appears to be training hard ahead of his side's last game of the year on December 30. Second-placed Al-Nassr travel to fourth-positioned Al-Taawoun, looking to cut the gap to league leaders Al-Hilal - who have a seven-point lead. Ahead of that match, Ronaldo has shown the remarkable shape he is in a couple of months before he turns 39.
