Masri maintained their fine run under coach Theo Buecker and widened the misery of second-bottom Mansoura with a 1-0 victory in the Egyptian Premier League on Wednesday.
The Port Said-based club, who eased their relegation worries with a 1-0 win over Asyut Petroleum last week, beat another relegation-threatened side in Mansoura to extend their unbeaten run to three games.
Lively playmaker Abdul-Salam Nagah, who has put in some impressive displays with Masri since joining in the January transfer window, scored the winner five minutes after the restart.
He also found the net in the team’s win over Asyut.
Masri have suffered just one defeat in eight matches since German coach Buecker, who also had spells with Zamalek, Ittihad and Ismaili in Egypt, took over at the club late in January.
