As the final whistle blew, a visibly upset Ronaldo was seen throwing his captain's armband to the ground after being unable to help his side retain their European title.
Then, as he made his way towards the tunnel, he dropped the armband again and kicked it, seemingly in frustration.

Portugal boss Fernando Santos later spoke of his team's disappointment at being dumped out of the competition.
"There are players crying in the changing room. They gave everything," he said, according to the Daily Mirror.
"Belgium had six shots, we had 29. Sincerely I don't have many words.
"We believed if we won this one, we would have gone on to win the next one.
"They scored, we didn't. It's football."
