Cristiano Ronaldo appeared to react furiously after fans chanted Lionel Messi's name during Al-Nassr's 1-0 defeat against Al-Ittihad.
The 38-year-old cut a frustrated figure as his Al-Nassr side were beaten in the top-of-the-table clash at the King Abdullah Sports City Stadium. Romarinho's second-half effort separated the two teams as Nuno Espirito Santo's men leapfrogged their opponents to move one point clear at the top of the Saudi Pro League.
After the game, a dejected Ronaldo could be seen shaking his head and ignoring his teammates' attempts to calm him down. The former Manchester United forward applauded the travelling Al-Nassr supporters before storming down the tunnel, ripping his captain's armband off and lobbing a bottle at the floor.
