Wales manager Chris Coleman has talked up the quality of Cristiano Ronaldo ahead of his side's Euro 2016 semi-final against Portugal.
The three-time Ballon d'Or winner is yet to hit top form in the competition, but Coleman recalled from personal experience that he can be "unstoppable" on his day.
However, Coleman also insists that Wales have their own world-class talent in Gareth Bale, who will be coming up against his Real Madrid teammate on Wednesday.
"If I speak to Giggsy (Ryan Giggs) or if you hear Alex [Ferguson] speaking about [Ronaldo], it's about his desire to get better. You see how motivated he is for himself to score, and to win. I constantly have conversations with players who say they played up to a certain level and were brilliantly talented, but if you look a bit deeper he was missing something: attitude or mentality," Coleman told reporters.
"With all his talent, Cristiano has that mentality. I remember Ronaldo when I was at Fulham as a manager, and he scored in the last minute, beat us 2-1 when we were fine and comfortable, went on a mazy run... unstoppable.
"You remember things like that, great pieces of play from great individuals. They've got one of them. We've got one too."
The match will be Wales's first ever appearance in the semi-finals of a major international tournament.
