Neither player is a regular member at Arsenal at the moment, but still enjoy each others company.
While generally a happy camp there are certainly a couple of players who are not best pleased at Arsenal currently.
Both had excellent summers in Brazil, Campbell leading the line for surprise package Costa Rica and Podolski playing a part in World Cup victory for Germany.
However neither is currently a regular in the Arsenal first-team.
Campbell has played just 37 minutes of football since returning from his loan spell at Olympiakos. Despite confirming himself that he wishes to remain at Arsenal his agent has been saying different - suggesting he wants a winter exit.
Podolski has made no secret of his unhappiness at his current Arsenal situation. He is fed up of not playing regular football and wants a move.
So this unhappy pair were entitled to look glum on the Arsenal bench yesterday.
But they didn't. It seems they kept each other in good company at The Hawthorns, sharing a laugh and a joke on the bench.
Arsenal fans will certainly hope to keep hold of both men. Hopefully they manage to keep each other happy at The Emirates.
