Cristiano Ronaldo was dropped to the bench for Portugal’s World Cup last-16 clash with Switzerland.
The 37-year-old left Manchester United last month under a cloud and has cast a shadow over Fernando Santos’ side during their time in Qatar, too.
Portugal head coach Santos was unhappy with the veteran’s reaction to being substituted towards the end of Friday’s 2-1 loss to South Korea.
Ronaldo said his frustration was aimed at an opposing player.
