Manchester United legend Gary Neville feels today's clash at Old Trafford is a test of Arsenal's title credentials.
Neville wrote in the Mail on Sunday: "The visit to Old Trafford is a crucial test. In their last campaign, Arsenal didn't win any of their games against last season's top three clubs, losing four and drawing two. Until now they haven't come up against any of those teams - which might account for their five-point lead at the top.
"It's why there are still questions as to whether they have the endurance to sustain this campaign. By that I mean the mental staying power to get around obstacles - like a cold day in January when you're drawing 0-0 with a minute on the clock, but end up taking all three points.
"Are they ready for the inevitable bad patch, the successive defeats? Title-winning teams don't dwell on defeats but react decisively.
"Arsenal still have much the same group of players that were celebrating finishing fourth on the last day of the season as though they had won a cup final. However, teams do mature and develop a mental strength."
