- Alexander Medina's side have the third-lowest average number of opposition touches inside their penalty area in the CONMEBOL Libertadores, while Flamengo head into the semi-final first leg as the only team averaging more than two direct attacks and two build-up attacks per match.
- The Argentine side have conceded just seven goals in ten matches and are one of two semi-finalists yet to concede more than once in a single game.
Estudiantes' challenge in the CONMEBOL Libertadores semi-finals starts with a clear priority: protecting their penalty area against one of the competition's most complete and versatile attacks. Defending champions Flamengo can progress directly up the pitch or build their moves patiently, but the La Plata side have already shown they can limit their influence in the most dangerous areas.
Across their ten matches in this edition, the 'Pincha' have allowed opponents just 132 touches inside their penalty area, an average of 13.2 per game — the third-lowest figure since the group stage began. At home, where the Argentine side are particularly strong, that number drops to eight.
One of the clearest demonstrations of this trend came in the second leg of the 'Eternal Glory' quarter-finals. In São Paulo, Estudiantes dominated Corinthians and allowed them just three shots inside their own penalty area, including the penalty Memphis Depay missed in the closing stages.
Eros Mancuso, Santiago Núñez, Leandro González Pírez and Tomás Palacios formed the defensive unit that shielded the goal guarded by Uruguayan goalkeeper Fernando Muslera and helped the Argentine side return to the CONMEBOL Libertadores semi-finals after a 17-year wait. Their previous appearance at this stage came in the 2009 edition, which ended with them lifting the trophy against Cruzeiro.
That defensive strength is also reflected in the 'León's' campaign in the continent's most prestigious club competition. Estudiantes have conceded seven goals in ten appearances and have never let in more than one in a single match. Defending champions Flamengo are the only other side among the four semi-finalists to share that record, although their figures are even tighter, with just five goals conceded in the same number of games.
This tie, however, presents a different kind of challenge. Flamengo are the only team in the competition to average more than two direct attacks and two build-up attacks per match. That combination allows them to threaten through quick transitions as well as carefully constructed possession moves. Faced with such variety, Estudiantes will look to repeat the approach that already proved effective in the group stage.
In the 1-1 draw in La Plata on matchday three, the Argentine side restricted the Rio de Janeiro outfit to 39 passes in the final third, their lowest total of the entire campaign. Luiz Araújo put the Brazilian side ahead in the first half, before Guido Carrillo, Estudiantes' all-time leading scorer in the competition, levelled the match after the break. When the sides met again on matchday five, Pedro scored the only goal as the Mengão claimed a 1-0 win at the Maracanã.
The previous meetings show that the Argentine side can restrict the space available to an opponent with several attacking options, while also highlighting how difficult it is to maintain that level of control for the full 90 minutes.
Against the defending champions, the 'Pincharrata' will be looking to reverse their recent record against Flamengo. In addition to the two group-stage meetings in this year's edition, the 'Fla' also knocked them out on their way to winning the title in 2025. The first leg in Rio de Janeiro ended in a 2-1 victory for Flamengo, before Estudiantes won 1-0 in the return fixture during normal time to take the tie to a penalty shoot-out. Agustín Rossi, the Brazilian side's Argentine goalkeeper — who spent time at the La Plata club between 2015 and 2016 — saved two penalties to become the hero of the tie.
