After 116 minutes in which neither side could muster a shot on target, the attacker pounced on the rebound of a Cristiano Ronaldo shot and headed his side into the next round
Ricardo Quaresma was the hero for Portugal as he scored the winning goal late in extra-time as Portugal beat Croatia 1-0 on Saturday.
The two sides played out a dull affair in which neither team mustered a shot on target until Quaresma rushed in to head over the line in the 117th minute.
Croatia had just strick the post at the other end but failed to convert the danger, allowing the Seleccao to lunge forward with a counter attack.
