Arsenal face Chelsea in the Premier League's headline clash this weekend, knowing defeat will inevitably re-open questions over their poor away form and their consistently bad results against top six rivals.

Therefore, it's imperative Arsene Wenger's selection and tactics are perfect when the Gunners travel to Stamford Bridge on Sunday to take on the reigning champions.

But the Arsenal boss has at least one huge decision to make in that regard - whether his side should line up with three or four at the back.

On the one hand, Arsenal were ripped apart at Anfield using 3-4-3 during the international break, and after going 1-0 down to FC Koln in midweek, they eventually won the Europa League tie after switching to a 4-2-3-1 in the second half.

On the other, Arsenal's record against Chelsea under Conte is actually very strong, winning in the FA Cup final and the Community Shield having matched up with the Blues' 3-4-3 on both occasions.

With that in mind, we asked Arsenal supporters earlier this week how Wenger should set up his side and our poll revealed that Gunners fans are incredibly divided on the issue, with three at the back edging the results by a 9% majority.
