Arsenal No2 Pat Rice says Robin van Persie needed a breather for last night's Champions League win over Olympiakos.
Arsenal went with Marouane Chamakh to lead the attack.
Rice explained: "Robin's been playing a lot of games lately and it was just a question of Chamakh needing games. We just thought that we would give him a go. You can't say that Marouane didn't try.
"If he had a little bit more luck he perhaps might have scored a third goal. But you cannot fault him for his work ethic."
