A thrilling 3-3 draw with Hungary at UEFA Euro 2016 last summer put Portugal into the knockout rounds and on their way to a first-ever triumph at a major tournament.
On that day back in June, Cristiano Ronaldo netted twice, and Portugal will hope their talisman is on form once again when they face Hungary in Saturday's qualifying clash for the 2018 FIFA World Cup.
A victory for Fernando Santos' side in Lisbon would see them, at worst, remain second in UEFA Group B, but a defeat would see Hungary leapfrog Portugal in the standings.
