Managed to catch second half yesterday - thought some serious plus points for the gunners! Adebayor looked really dangerous and up for it - pretty good shout for prem's leading scorer methinks. Walcott looked pretty good to, and Wilshere was really talented for his age.
Only downside was Diaby 'well patrick vieira was always allowed to tackle from behind so I guess I can too' ruining Sneijders season. Personally up to that point i was impressed with teh aggresiveness of the Arsenal defending, they were really going in with challenges, but thought Diaby's was waaaayyy over the top for a friendly. How the ref missed I do not know.
But I would say your first XI will challenge on all fronts. The problem will be injuries, particularly to Gallas/Toure
