Portugal

Cristiano Ronaldo, who has just won a Champions League and Premier League double with Manchester United, could complete a remarkable treble of winners' medals by leading Portugal to victory in Euro 2008 this month. The 23-year-old winger, who scored 42 goals in all competitions for United last season, will be the key as Portugal look to ease their way past co-hosts Switzerland, the Czech Republic and Turkey in Group A in Basel and Geneva.

Fans at those two venues will be in for a special treat if he recreates his club form for his country, who head into the tournament free of the pressures that burdened them somewhat as host nation four years ago.

They froze in the final and were beaten by big outsiders Greece in Lisbon. Prior to that, Portugal had appeared in two semi-finals, in 1984 and in 2000, where they lost on both occasions to France.

Portugal, who are coached by Brazilian Luiz Felipe Scolari, should have the class to finish in one of the first two places from the quartet and qualify for the quarter-finals, probably with the Czechs.
