World Cup co-hosts Mexico have enjoyed the perfect progress with three wins to top their group but they face a stern test as Ecuador come to the Azteca Stadium in the last 32.
Mexico are sure to be confident after winning all three group games at a World Cup for the first time, while their formidable record at their national stadium is a further source of confidence.
Ecuador can also bring an upbeat mood, as they had to come from behind in a must-win group finale against European powerhouses Germany just to grab the 2-1 win that staved off their elimination.
Mexico and Ecuador take to the field at the Azteca Stadium for what should be an occasion laced with passion and desire, but, perhaps also one burdened by caution.
Seven of Ecuador's last eight competitive games have gone under 1.5 goals, with El Tri conceding just twice in the last 11 games played. They have yet to leak a goal at this World Cup.
Ecuador are a low-scoring but superb side defensively. The two goals they scored in recovering from an early concession to beat a German side already assured of top spot in Group E were their only goals in three group games.
A particular source of concern was their failure to break down Curacao in Kansas despite registering 15 shots on target.
In CONMEBOL qualifying, the Ecuadorians conceded only five times in 18 games and they will be very tough to break down again now.
Both teams have scored in just one of Mexico's last six games, while 13 of Ecuador's last 16 games have produced two goals or less. The last three meetings of these teams have produced just two goals combined.
The most recent meeting of these nations came in October last year and it ended 1-1 at the Estadio Akron in Zapopan.
That made it three successive draws, following a 2022 friendly at Soldier Field in Chicago and the 2023 Copa America group phase stalemate that sent Ecuador through to the quarterfinals at Mexico's expense.
Ecuador under Sebastian Beccacece are masters at keeping games tight. If they can keep the scores level for the bulk, Mexico's unwillingness to make a tournament-ending error can also take over and it is worth noting this will be the 10th World Cup game for El Tri at the Azteca and, so far, they have conceded just two goals in nine.
Should this go the distance, Ecuador will face a wall of noise in a possible penalty shootout in front of the passionate home support and the hosts might find added composure.
With Ecuador likely to defend quite deep with numbers behind the ball, Mexico are going to have to work hard to engineer chances.
Wide man Julian Quinones has scored two of their six goals in this tournament. He has taken 10 shots across three games, with four of those on target.
He scored 33 goals for Saudi Pro League side Al-Qadsiah in the 2025/26 season, beating England's Ivan Toney (32) and Portuguese icon Cristiano Ronaldo (28) to the golden boot.
If Ecuador do form a low block and make space optimal for Mexico's attackers, some speculative shooting from distance will appeal and Quinones is capable of a couple of efforts on target.
