The on-loan Stoke City striker opened the scoring with a firm header on six minutes before the Moroccan made sure of an Eagles win with a clinical finish after the break
Tony Pulis paid tribute to match-winners Marouane Chamakh and Cameron Jerome after Crystal Palace comfortably saw off Cardiff City at Selhurst Park.
Jerome headed the Eagles into the lead on six minutes with his first goal since February, while Chamakh finished with aplomb just before the hour mark to make sure of the points.
And Pulis insists their goals are a fitting reward for the way his two much-maligned strikers have applied themselves in training and matches.
"Those two have been brilliant and really given everybody in the team a lead in the way they worked," Pulis told reporters of Chamakh and Jerome.
"Chamakh was wonderful, his link-up play was very good and Cameron’s a threat to anybody.
"Chamakh has got real quality. Arsenal never buy a player unless he’s got quality. Wenger knows who’s got quality, and Chamakh has it. It’s just a matter of getting it out of him.
"I don’t think he’s ever been a problem, he’s just lost his way a little bit. When you’re at top, top clubs you don’t get a lot of time. You have to be doing it because the top clubs are under so much pressure.
"In the games I’ve seen he’s really looked up for it and he’s played well.
"He recognises he’s an important member of this group, and hopefully he keeps playing the way he’s playing."
Cardiff boss Malky Mackay, meanwhile, lamented his side's poor finishing after a result which leaves them just one point ahead of Palace following a run of one win in nine matches.
"We certainly weren’t at it the way we have been but even then it’s about taking chances," he insisted. "In the first five minutes we should have scored, and goals change games.
"In the second half we had two headers that we didn’t connect with either, and then Chamakh gets a free strike in the box.
"Overall we want to be better than we were but we had three chances in the six-yard box away from home which we should score from."
