West Ham United striker Marouane Chamakh says his new teammates must play with passion to get something from Arsenal tonight.
Chamakh is on-loan at the Hammers from Arsenal and will be ineligible for the game.
"I don't know if I necessarily have any secrets [about Arsenal]," he said. "The players will have to produce something pretty good over there.
"They're going to play with their hearts and their heads and they'll have to give everything to bring us back at least a point."
