Northern Ireland left-back Ryan McGivern says he has taken plenty of confidence from last month's meeting with the likes of Cristiano Ronaldo and Nani.
The Manchester City defender, who is on loan at Hibernian, helped his country to a 1-1 draw with the Portuguese in World Cup qualifying and he is now looking ahead after performing well in such a massive test.
"Personally it was a great experience, probably one of the highlights of my career so far," said McGivern.
"It's given me a bit of confidence. Marking two of the top wingers in the game, Nani and (especially) Ronaldo, who's one of the best players in the world along with Lionel Messi.
"If I managed to keep those two quiet enough for 90 minutes it gives me a lot of confidence for the rest of my career.
"It was a great team performance - Portugal were ranked three in the world at the time - and for us to go there and get a point was great."
