Shillong Lajong inflicted a comprehensive 3-0 defeat on Diamond Harbour at the Naihati Stadium, a result that the Lemeister model, which had installed the home side as narrow favourites at 39 per cent, did not anticipate. The final scoreline was dictated by a ruthless first-half display that established a two-goal cushion before the interval, after which a third goal early in the second half ended any prospect of a Diamond Harbour recovery. The model's projection of a 2-1 home win was rendered inaccurate by the visitors' clinical efficiency in front of goal and their ability to suppress Diamond Harbour's attacking threat.
The opening goal arrived on the half-hour mark, when E. Mylliempdah converted from an assist by F. Syndai to give the visitors the lead. The advantage was doubled in first-half stoppage time, as G. Kharbuli found the net with help from P. Buam, leaving Diamond Harbour with a significant deficit at the break. The timing of the second goal was particularly damaging, denying the home side the opportunity to reorganise during the interval with only a one-goal deficit. The pattern of the second half was set early when P. Buam turned goalscorer in the 53rd minute, this time assisted by L. Vaiphei, completing Shillong Lajong's scoring inside the opening eight minutes of the second period. That quick strike after the restart effectively extinguished any hope of a Diamond Harbour comeback.
The match's disciplinary record saw Diamond Harbour's G. Khosla booked in the 27th minute, while L. Vaiphei of Shillong Lajong received a yellow card in the 82nd minute. A further yellow card was issued to an unidentified Diamond Harbour player at the start of the match, indicating the home side's early struggles to contain Shillong Lajong's attacking movements. The five substitutions made by each side suggested both benches were utilised in an attempt to influence the game's momentum, though neither set of changes altered the trajectory of a contest that had been decisively shaped in the first hour.
The impact of the goalscorers and their providers is clear from the sequence of play. P. Buam was central to the victory, scoring once and providing the assist for G. Kharbuli's strike, making him the most influential player on the pitch in terms of direct goal contributions. F. Syndai and L. Vaiphei also contributed assists, while E. Mylliempdah opened the scoring with the crucial first goal that settled any early nerves for the visitors. These four players formed the core of Shillong Lajong's attacking threat, creating and finishing the chances that ultimately decided the contest. Diamond Harbour's inability to respond after conceding the third goal early in the second half underscored their struggles against the visitors' efficiency in the final third. Despite the absence of detailed possession, shots and expected goals data, the clean sheet and the three-goal margin indicate that Shillong Lajong were largely in control after establishing their early lead, limiting Diamond Harbour to a match where they failed to find the net despite being the pre-match favourites.
The result leaves Shillong Lajong with a valuable three points in the I-League Promotion Group, a competition context where every point is critical in the race for promotion. Diamond Harbour, on the other hand, will be disappointed to have lost at home, particularly having been the pre-match favourites according to the Lemeister model. The victory not only narrows any gap between the sides in the standings but also provides Shillong Lajong with a significant boost in momentum as the group stage progresses. For Diamond Harbour, the challenge will be to recover from this setback and address the defensive vulnerabilities that allowed three goals to be conceded without reply. The comprehensive nature of the defeat, against a side given only a 33 per cent chance by the model, raises questions about the home team's ability to meet expectations in this promotion group campaign.
