What have been each team's routes to this stage?
Uruguay topped group A, going about their business quietly and efficiently. Wins over Egypt, Saudi Arabia and then hosts Russia – without conceding a goal – have almost gone unnoticed. Actually, they look pretty good to go deep into this tournament.
Portugal, meanwhile, were involved in the game of the tournament so far on day two – the 3-3 draw with Spain – but it has not been as easy going since, a narrow win over Morocco and a draw with Iran seeing them through to the knockout rounds.
What is the team news?
Both teams could name unchanged line-ups on Saturday, though we will find out more details in the next 24 hours.
What's the latest news on the two teams?
Portugal coach Fernando Santos brushed aside various video assistant referee (VAR) decisions and a sub-par performance from Cristiano Ronaldo to stress his players achieved their main goal in a 1-1 draw with Iran by qualifying for the World Cup last 16.
The result, combined with Spain's 2-2 draw with Morocco and an earlier win for Uruguay over hosts Russia in Group A, means Portugal will play Uruguay in Sochi on June 30, while Group B winners Spain will face Russia in Moscow on July 1.
"The important thing is to think about the [round of 16] match, think about the game, get to know your adversaries and then to get well prepared mentally and physically, regardless of it being Uruguay or the hosts," Santos said of his team's progress.
"These are different circumstance of course, the hosts have huge support and they've had a very good tournament, while Uruguay has high quality and top-notch players and they're all excellent – but Portugal too. We have our weapons and we're going to try to win."
Ricardo Quaresma put Portugal ahead just before halftime with a lovely goal from outside the box before Ronaldo missed a chance to double their lead eight minutes into the second half when he missed a penalty awarded with the help of VAR.
At the other end, Karim Ansarifard got an equaliser for Iran in stoppage time after the referee awarded a second VAR-assisted penalty for handball.
The referee also consulted VAR before deciding not to send Ronaldo off after he raised an arm to Morteza Pouraliganji in the centre of the field while chasing a long ball.
People like Ronaldo "want to be the best and when they fail they get upset," Santos said of the Real Madrid forward, who looked agitated by the tight defending and his lack of opportunities.
"I wasn't concerned (by the three VAR decisions)," Santos added. "It seemed like a normal thing in the match. The referee did what he had to do. I think the VAR did its job and that's what we have to accept."
What are the odds?
- Uruguay win – 7/4
- Portugal win – 9/5
What's our prediction?
Blood, sweat and tears. Then a very tight encounter, edged by Uruguay's attacking prowess.
