The league newcomers stood their ground against Ahli, until a second half Ahmed Duiedar spot-kick handed them the crucial win over the African and Egyptian champions.

"I'm really happy with the way we played today. We put Ahli under pressure right from the start, and that was the key behind halting their attacks," Youssef told Modern Sport TV.

"The performance in my opinion was more important than the result, as we showed a lot of confidence and composure against the African champions.

"We will definitely try to build on today's win in the next league games."

The massive win lifts Police to eleventh spot in the table with 14 points from 12 games.
