Birkir Bjarnason's volley earned a valuable draw for the Scandinavian side after former Manchester United man Nani opened the scoring in St-Etienne.

But Ronaldo was not impressed with the way Iceland decided to approach the match.

The Real Madrid superstar said: "It was a little bit frustrating, we tried hard to win the game, Iceland didn't try anything.

"They scored a goal, they created two chances in the 90 minutes and otherwise they got every player behind the ball, they put the bus in the net.

"So it's difficult when one team don't try, but Portugal try and play football and try to win the game.

"Iceland didn't try anything, they were just defend, defend, defend and playing on the counter-attack. It was a lucky night for them."

Ronaldo also criticised Iceland’s celebrations at the end of the match after earning their first point in European Championship football.

He added: "I thought they'd won the Euros the way they celebrated at the end, it was unbelievable.

"When they don't try to play and just defend, defend, defend, this in my opinion shows a small mentality and they are not going to do anything in the competition."

Up next for Portugal is a clash against Austria who lost their first match to Hungary 2-0.
