Kalba claimed a dramatic 2-1 comeback victory away to Dibba in Matchweek four of the ADNOC Pro League, overturning a first-half deficit with a stoppage-time winner.
Dibba took the lead in the 17th minute when Iago Santos rose highest to head home. They nearly doubled their advantage shortly after, but Mohanad Ali missed a clear chance in the 25th minute.
Kalba returned stronger after the break and equalised in the 53rd minute through Renny Rivas, who became the third Venezuelan player to score in the ADNOC Pro League after Jesús Meza and Gelmin Rivas.
The game appeared set to finish level until the 92nd minute, when substitute Ahmed Shehda Abunamous unleashed a powerful strike from outside the box to secure all three points for Kalba.
The win lifts Kalba to sixth place in the standings with seven points, while Dibba remain at the bottom without a point.
