Micah Richards has claimed that Portugal might have a 'problem' with Cristiano Ronaldo after the veteran forward played in all three group stage matches. 

Ronaldo is yet to score at the tournament and it's been suggested that his desire to play in their final group fixture was down to his goal drought, which Richards says could be an issue. 

He was withdrawn by Martinez after 66 minutes, replaced by Goncalo Ramos, but didn't take the substitution well as he lashed out, kicking the turf as he made his way to his seat.

The 39-year-old received a pat on the back from Martinez, looking down and appearing frustrated as other members of the Portugal coaching staff patted him on the back.
