The start of Round 4 brought together Medenballers and Retainers AFC in a match of huge significance. Sitting fourth and fifth respectively, both teams knew that victory would give their hopes of Plate qualification a major boost heading into the final round of group matches. With so little separating the sides in the standings, this had all the ingredients of a fiercely contested encounter.

It was Medenballers who made the brighter start and struck first through the in-form Thomas Quentin Beller. His third goal of the tournament rewarded the Dutch side for an encouraging opening and gave them the ideal platform. However, Retainers AFC responded almost immediately. Massi Ghiani levelled the scores before producing an excellent free-kick to complete a rapid turnaround. In the space of a few minutes, the English side had transformed the contest and went into the interval leading 2–1.

The second half was a much tighter affair, with Retainers AFC showing excellent maturity to protect their advantage. Rather than going gung-ho chasing additional goals, they managed the game intelligently, frustrating Medenballers and limiting them to very few clear opportunities. Their disciplined defensive display ensured there would be no way back for the hosts, and the score remained unchanged until the final whistle.

The 2–1 victory handed Retainers AFC their first win of the tournament at a crucial moment, keeping their knockout hopes firmly alive going into the final round of fixtures. For Medenballers, it was a disappointing setback after taking the lead, leaving them with plenty to do in their final group game if they were to extend their Amsterdam Sixes campaign.

With Hilfe FC having already secured another victory, the pressure was firmly on Humble Goats to keep pace at the top of Group B. Their opponents, Joga Bonito, occupied third place and had won two of their opening three matches, meaning this was far from a routine assignment. A Romanian victory would pull them level on points with Humble Goats and leave Cup qualification finely poised heading into the final round. For Humble Goats, however, three points would not only preserve their perfect start but also guarantee Cup qualification alongside Hilfe FC with a game to spare.

One of the defining features of Humble Goats' campaign had been their exceptional first-half form, and that trend continued once again. Jazz Prins maintained his outstanding scoring record by finding the net for the fourth time in the tournament to give the Dutch side the lead. It meant Humble Goats had now scored ten first-half goals without reply across their opening four matches, a statistic that underlined their ability to seize control of games early and build the foundations for victory.

To their credit, Joga Bonito remained competitive throughout and ensured there would be no comfortable afternoon for the Dutch side. The Romanians pressed for an equaliser and showed the same organisation and resilience that had earned them two wins earlier in the day. However, Humble Goats defended superbly, with Jamal Oulad Mhand Aissa keeping another clean sheet and protect their slender advantage until the final whistle. The 1–0 victory was a huge result for Humble Goats. It maintained their perfect record, moved them onto 12 points, and secured their place in the Cup competition with a game to spare alongside Hilfe FC. For Joga Bonito, the defeat was a setback, but they remained firmly in contention for a knockout place heading into the final round, knowing that their strong performances throughout the group stage had still left them with everything to play for.
