Portugal 
Fresh from a fantastic season with Manchester United, the mission for Ronaldo this summer is to set the international stage alight.
It is hard to fault somebody who scored 31 goals in the Premier League from midfield, had numerous other assists and plays with such swagger and flair that he is also one of the great entertainers in world football, still at the age of 23, but criticism often follows success.
One complaint that has been levelled at Ronaldo in the past is that he does not always produce against the best opponents, which again seems unfair considering that he has scored against Liverpool, Arsenal and Roma in the last three months alone, and also netted in the UEFA Champions League final.
Euro 2008 nevertheless represents the perfect opportunity for Ronaldo to showcase his dazzling skills for a global audience and strengthen his case to be recognised as the greatest player of his generation.
He is undoubtedly the talisman of the Portuguese side and made such an impact in the qualifying campaign that Luis Figo, who retired after the 2006 World Cup, was barely missed.
Ronaldo scored eight times on the road to Austria and Switzerland to take his international tally to 20 from 54 games, another impressive return in a team that has not been prolific under Scolari.
The winger has a solid if unspectacular history in major tournaments, helping Portugal to the final four years ago and then the semi-finals of the World Cup in Germany.
He has received abuse from rival fans in the Premier League after winking at his bench when Wayne Rooney was sent off in Portugal's quarter-final with England, but his performances have not been affected.
A player who was once described as 'having no end product' seems to be going from strength to strength and it would take a brave person to bet against him being the star of the show at the European Championship.
