With Cristiano Ronaldo on the bench, the superstar striker’s replacement scored a hat trick to lead Portugal over Switzerland 6-1 and into the World Cup quarterfinals today.

Goncalo Ramos, a 21-year-old forward who only made his Portugal debut last month, made his first start for his country and demonstrated the kind of clinical finishing Ronaldo was once known for.

Ramos scored the opening goal in the 17th minute and added others in the 51st and 67th — by which time chants of “RONALDO! RONALDO!” were swirling around the 89,000-seat Lusail Stadium.

The 37-year-old Ronaldo entered as a substitute in the 72nd minute to loud cheers, though Portugal had the game wrapped up by then with defenders Pepe and Raphael Guerreiro also scoring. Rafael Leao added a another goal in stoppage time.

Manuel Akanji scored for Switzerland.

Portugal advanced to the quarterfinals for the third time, after 1966 and 2006, and will play Morocco on Saturday.

Portugal coach Fernando Santos now has to decide whether to stick with Ramos or restore Ronaldo, the top scorer in men’s international soccer and one of the game’s greatest ever players.

Ronaldo had a couple of chances after coming on, and even thought he had scored when he ran through and drove a low shot past Switzerland goalkeeper Yann Sommer. The goal was disallowed for offside, much to the irritation of the fans — Portuguese or from other countries — who had come to see him.

After the final whistle, as Portugal players stayed on the field to applaud the team's fans at one end of the stadium, Ronaldo walked off on his own — perhaps wondering where his career goes from here. He is currently without a club after leaving Manchester United midway through the World Cup.

Ronaldo was dropped a day after Santos expressed his unhappiness at the striker's attitude after he was substituted against South Korea in the team's final group game.

Ramos was a surprise replacement — he had previously only made three substitute appearances for Portugal — and took his chance.

Ramos, who was only 2 years old when Ronaldo made his Portugal debut in 2003, produced the first hat trick at this year’s World Cup. He also did something Ronaldo has never achieved — score a knockout goal at soccer’s biggest tournament.

Ramos drove a rising shot with his left foot inside Sommer’s near post for the first goal, flicked deftly through Sommer’s legs from close range for the second, and then ran through to chip the goalkeeper for his third.

Ronaldo was seen smiling while he was warming up on the side of the field after Ramos' second goal.

Ramos even had an assist, playing the ball through for Guerreiro to score the fourth goal.
