The 21-year-old winger has a great chance to show Arsene Wenger he has improved as a player when he goes back to Highbury with Leeds tomorrow night. "I've never stopped believing that one day I will be part of things at Arsenal," said Pennant. "If I do well in front of the Arsenal fans and the manager, that can only be good for me in the long run. It's tough at Arsenal. You look at the midfield, it's full of international players and that makes it difficult to force your way in."
