Podolski struck in last night's win over Olympiakos.
"Lukas is a fantastic worker and he's a great player as well," Gibbs told arsenal.com. "He's a joy to work with. The fact that he works so hard inspires me to work hard as well. He brings that to the team. He's a very important player for us and he's producing goals, he's defending well, he's attacking well. It's a pleasure to work with him."
