Ronaldo looks to shine tonight

DOHA, Qatar (Agencies): Kylian Mbappé is the top scorer. Lionel Messi has been thrilling fans with his goals and dribbles. So what about Cristiano Ronaldo, one of the other superstars at the World Cup?
He has broken a tournament record by becoming the first player to score a goal at five World Cups, but since converting that penalty in Portugal's opening game, Ronaldo has had a rather quiet time of it.
Maybe he's about to burst into life in the knockout stage - and erase a blemish in his glittering career: None of Ronaldo's eight World Cup goals have come in the knockout stage.
The five-time world player of the year heads into the round of 16 in likely his final World Cup facing Switzerland, which hasn't advanced beyond this stage since 1954.
This is the same Switzerland that eliminated France in the last 16 at the European Championship last year and has become one of its continent's most consistent teams.
Portugal might need Ronaldo to start delivering. And the player himself will surely want to put himself back in the spotlight, having seen Messi - his great rival - perform so well for Argentina in its win over Australia in the last 16 and Mbappé - the man who is fast establishing himself as the sport's new superstar - already rack up five goals for France on its path to the quarterfinals.
Still oozing self-confidence at the age of 37, Ronaldo continues to back himself to perform at the highest level, yet his last two performances in the group stage were underwhelming. His only goal so far has come from the penalty spot in Portugal's opening victory over Ghana.
Portugal won its first two group games to advance and little should be read into the loss to South Korea, given coach Fernando Santos rotated heavily - even if Ronaldo started for the third straight game.
He'll be playing for the fourth time in 13 days and that's quite the workload these days for Ronaldo, whose game time has been managed for the past year and a half at Manchester United.
Portugal coach Fernando Santos has been boosted by news that key midfielder Otavio should be fully fit and ready to play in their World Cup last-16 match on Tuesday.
After missing the last two games with a thigh injury, the Porto midfielder will join his team mates for training on Sunday for the first time since their opening win over Ghana.
Centre half Danilo Pereira, who sustained three broken ribs last week, is also recovering well and could feature later in the tournament.
His replacement in the last two matches was 39-year-old defender Pepe, who is likely to keep his place and be tasked with marking Swiss striker Breel Embolo, who has scored twice in the tournament.
Pepe will be paired with Manchester City centre back Ruben Dias, who was rested for their last group match against South Korea which Portugal lost 2-1.
Santos was forced into a change at left back after Nuno Mendes was ruled out of the World Cup due to an injury suffered in the first half against Uruguay.
Santos switched Joao Cancelo to the left and brought in Diogo Dalot at right back and the coach is expected to keep the same formation against Switzerland.
Captain Cristiano Ronaldo will bid again to equal the record of World Cup goals scored for Portugal held by Eusebio, who racked up nine in 1966 in England.
Switzerland have their own forward seeking a place in the record books.
Xherdan Shaqiri's goal against Serbia in the group stage meant he has found the net in more World Cup tournaments than any other Swiss player, having also scored in 2014 and 2018.
He is one goal away from matching the most World Cup goals scored by a Switzerland player - six, by Sepp Huegi all in 1954.
The Swiss quietly finished second in their group behind Brazil, victories over Cameroon and Serbia earning their place in the last 16.
