Gunners boss Arsene Wenger and defender Johan Djourou praised the Morocco starâ€™s â€˜presenceâ€™ during the Emirates Cup last weekend.
"He had an intelligent game and was a good presence up front," said the Arsenal boss after Chamakh scored on his home debut in a 1-1 draw with AC Milan. "I believe he did very well. We wanted a player who could play for the team up front and get involved in combinations."
Djourou added: "He can do a lot with his presence. Heâ€™s a big guy, good with his feet, powerful and good in the air."
