A 89th minute strike from Lama Kone earned ENPPI a 1-0 away win over Dakhleya on Monday to extend their lead at the top of the Egyptian Premier League.
The oil-company team grabbed their eighth victory in 11 games to move four points clear at the top ahead of second-placed Zamalek, who will play Maqassa on Tuesday.
A late blunder by veteran keeper Ahmed Fawzi, who failed to clear a long ball from inside the area, found Mahmoud Kaoud who set up Kone inside the box with the goal at his mercy.
Dakhleya dropped to ninth place in the table with 16 points, just behind Ismaily who claimed a 2-1 away win against Assiouti Sport earlier in the day.
Ghanaian striker John Antwi broke the deadlock in the 76th minute to score his 10th league goal and move clear on top of the scorers' chart. Skipper Hosni Abd-Rabou doubled the lead six minutes later before Teddy Adams scored a consolation goal from the spot in the dying seconds of the game.
In Ismailia, Mahmoud Sayed fired a 93rd minute stunner for Gouna to sink Masry and climb to 12th place with 14 points, three above the danger zone.
After 12 rounds, newcomers Damanhour claimed their first ever league win after beating Ragaa 2-1. However, they remain third from the bottom with only six points and are likely to finish the season among the five relegated teams.
