The Portuguese brothers Martim and Francisco Costa caused major problems for GOG's defense, which had no answer to their stylistic performance. Together, the Costa brothers scored 20 goals and secured the victory for Sporting.
As a result, GOG finds themselves at the bottom of the group alongside Sweden's Kristianstad after the opening round.
The Portuguese home team quickly took the lead, establishing a 10-5 advantage over GOG by the midway point of the first half. GOG lacked the efficiency in scoring and were intermittently overrun by Sporting’s counterattacks.
Martim Costa dominated the game, converting almost every shot, allowing the team to head into the break with a comfortable 21-13 lead.
GOG returned for the second half with renewed energy, with both Oli Mittun and Manuel Zehnder scoring crucial goals to keep their team in the contest.
After their first double-digit lead at 26-16, the hosts decelerated, knowing the victory was secured. Steered by new arrival Manuel Zehnder and Olí Mittún, the Danish side managed to reduce the gap to five goals. But then Sporting found their rhythm again, scored fluently – and missed their Champions League high-score (44-31 against Kolstad in November 2025) by only one goal.
23-year-old Martim Costa finished the match with 11 goals, while 21-year-old Francisco Costa scored 9.
GOG and Mittun—who managed to score eight goals himself—could not match that performance. Consequently, the team from Funen opened their Champions League campaign with a heavy defeat.
