Arsenal travel to Old Trafford on Sunday as Premier League leaders to face a Manchester United team labouring somewhat under David Moyes and desperate to make a statement of intent.
The Gunners have a dreadful recent record at United, but they're arguably in ruder health now than they have been since the early days of Arsene Wenger's reign.
Aaron Ramsey and Mesut Ozil have inspired their midfield play, while Olivier Giroud has proven himself to be a world-class striker to lead the Arsenal line.
Arsenal beat Liverpool last weekend and followed that victory with a notable 1-0 scalp at Borussia Dortmund in the Champions League. These are heady times indeed for the Gunners, and the doubts are creeping away with every convincing performance.
United would love to dish out a reality check. Moyes' team have yet to turn on the style, but the results are starting to come and they are of course the defending league champions.
Here are five things to watch on Sunday.
