In the second game of the evening, Lionel Messi-led Argentina will try to overcome the Netherlands to set up a successful all-South American clash.
The two football powerhouses, Brazil and Argentina, have not met at the World Cup since 1990.
Neymar, who injured his ankle in his opener, is fit and shooting again.
“I will do everything possible to win with the Brazilian national team. This is our mission and our dream,” said Neymar.
“We are getting closer and closer, we have one more step to take now.”
Croatia are a much changed side from the one that reached the final four years ago, but 37-year-old Luka Modric remains the player who lets them beat.
“I agree we did a great thing getting to the quarter-finals, but regardless we would like to do more,” said Modric, who will face his Real Madrid teammates Vinicius Junior, Rodrygo and Eder Militao in the match at Education City stadium.
“We know the most important match is ahead of us. Brazil are always favourites. We have to be ourselves.”
Seven-time Ballon d’Or winner Lionel Messi is hoping to finally end his bid for a world title with Argentina, after losing the final to Germany in extra time eight years ago.
The Copa America holders will face the Netherlands in Friday’s second quarter-final at Lusail Stadium, venue of the final on 18 December.
The two nations have met five times at the World Cup, including the 1978 final, which Argentina won 3-1 after extra time. Argentina have never beaten the Dutch in 90 minutes.
It is a repeat of the 2014 semi-final in Brazil, where the South Americans won on penalties after a 0-0 draw after 120 minutes.
“In 2014 I was there too and things ended up a little differently (than we wanted), but I would like to change things now,” Dutch forward Memphis Depay said in a press conference before the match.
After Argentina’s sensational defeat to Saudi Arabia in their first match, Messi dazzled in Qatar and the Dutch will need to undo his effect on the game.
“We will not reveal our tactics to you (on Messi’s arrest). It would be quite stupid to reveal your own tactics,” coach Louis van Gaal told reporters.
“Messi is the most dangerous creative player, he’s capable of creating a lot and scoring himself. But when they lose the ball he doesn’t participate much, that gives us possibilities,” he said.
England received a boost ahead of Saturday’s showdown with defending champions France as Declan Rice returned to training following an illness.
Raheem Sterling will also join the squad on Friday after spending time in England following a robbery at his home.
Portugal have denied reports that Cristiano Ronaldo threatened to quit their squad after being substituted for a 6-1 defeat by Switzerland in the round of 16.
Ronaldo later took to social media to say Portugal were “too united to be broken by outside forces” ahead of their match with first-time quarter-finalists Morocco.
All-time top scorer in men’s international football with 118 goals, Ronaldo was eliminated in favor of Goncalo Ramos against Switzerland.
The 21-year-old Ramos justified Fernando Santos’ bold decision by scoring a hat-trick and providing an assist on his Portugal debut.
Morocco are looking to become the first African team to reach the bottom four at the World Cup.
Thousands of Moroccan fans took to the streets of Doha after Atlas Lions eliminated Spain on penalties in the round of 16.
“We managed to create a family and we feel that there is a whole country behind us,” said coach Walid Regragui.
“Feel this energy. It helps to perform like this.”
He added, “I’ve got a great group, they stick with what I say and they do it. I don’t know how far we’ll go.”
