St Etienne: Portugal forward Cristiano Ronaldo and defender Pepe could land roles in Hollywood because of their play-acting, Iceland coach Lars Lagerback has said ahead their European Championship Group F clash in St Etienne on Tuesday.

Iceland will be playing their first match at a major international finals against Portugal and Lagerback called for retrospective action against players who tried to dupe the referee, while naming Ronaldo and Pepe as serial offenders.

"Portugal have one of the best players in the world in Ronaldo but he's also an excellent actor," the 67-year-old told reporters in France, while remarking that the Real Madrid pair had play acted during the Champions League final last month.

"In the final of the Champions League against Atletico, we saw another performance from someone who could be in Hollywood. I mention Pepe. I mean, you can see the clips... For me, that is acting, really, of high class. But I don't know what demands they have in Hollywood. I don't like that. I'd like it if they were able to watch the videos to retrospectively punish that sort of thing.

Meanwhile, the resurgence of mercurial forward Ricardo Quaresma has raised Portugal's hopes even though it is still far from certain whether he will start against Iceland on Tuesday.

Quaresma was given a rare start in the final warm-up match against Estonia on Wednesday and responded with a virtuoso performance, even overshadowing Cristiano, as Portugal hit seven goals without reply.

There was a "trivela", a "rabona" and a stunning dinked goal and his exuberance rubbed off on his teammates as Portugal played with a verve that was missing from their qualifying campaign when they ground out seven successive wins by single-goal margins.

Coach Fernando Santos must now decide whether he wants to throw the always unpredictable Quaresma into the Euro 2016 fray, which would almost certainly be at the expense of former Manchester United forward Nani.

An attack featuring Quaresma and Ronaldo would make Portugal one of the most entertaining teams in the tournament but Santos, the wily former Greece coach, was making no promises even after the win over Estonia.

"It's not a case of Quaresma plus 10, it's Quaresma and another 22. There are 23 players in the squad and all have equal chances of playing but it's an excellent headache to have," he said.
