Flamengo U20 defeated Olimpia U20 2-1 in the CONMEBOL Libertadores U20 semi-finals, a result that the data shows was decided by superior attacking efficiency in the final third. The Lemeister model had given Flamengo a 44% win probability and projected a 2-0 scoreline, slightly overestimating the margin but correctly forecasting the winner. The match was decided by two first-half bookings for the home side and a decisive second-half strike, but the underlying numbers paint a clear picture of Flamengo's control.
Flamengo took the lead in the 12th minute when Ryan Roberto scored, assisted by Daniel Sales. Olimpia responded swiftly, equalising from the penalty spot in the 20th minute through F. Barone, after Daniel Sales had been booked for Flamengo three minutes earlier. The decisive moment arrived in the 73rd minute when Pablo Lucio converted an assist from Joao Souza to restore Flamengo's lead. The match became increasingly physical in its closing stages, with Olimpia defender O. Cardozo and Flamengo's Joao Souza both cautioned in the 75th minute, followed by a yellow card for Flamengo's Lucas Vieira in the 81st minute. Flamengo finished with four yellow cards to Olimpia's one, and their 14 fouls committed were four more than their opponents, reflecting an aggressive approach to regaining possession.
The statistical profile of the contest was shaped by Flamengo's greater control of the ball. They recorded 54% possession against 46% for Olimpia, and their passing accuracy of 82% was notably superior to Olimpia's 73%.

Flamengo also led the shot count 14 to 8 and had 6 shots on target to Olimpia's 3, underlining their persistent threat. The home side's set-piece and crossing effectiveness was a notable feature; they delivered 23 crosses to Olimpia's 9 and earned 7 corners to their opponents' 2, suggesting their wide attacking play was a primary source of pressure. Olimpia defended resolutely, making 26 clearances compared to Flamengo's 13, but could not prevent the decisive second goal from open play.
The player match ratings identified Joao Souza as the outstanding performer on the pitch with a rating of 8.2. His assist for the winning goal was the centrepiece of a display that included 4 key passes and 1 completed dribble, and he was also active defensively with 3 tackles won.

Pablo Lucio, the match-winner, earned a 7.2 rating, reflecting his timely intervention from an assist by the game's highest-graded player.
With this victory, Flamengo U20 advance to the final of the CONMEBOL Libertadores U20. Their efficient use of possession and superior chance creation, as reflected in the xG figures, proved decisive against an Olimpia side that fought tenaciously but could not match their creative output from open play. The Lemeister model's pre-match assessment correctly identified Flamengo as the favourite, though the actual margin of victory was tighter than the projected 2-0, underscoring the resilience of the Olimpia defence and the importance of individual moments of quality in knockout football. Flamengo will now seek to convert their statistical dominance into a trophy.
