Arsenal destroyed Chelsea 3-0 in their last meeting, scoring three goals in a first half blitz and prompting the Blues to return after the break with a new look three-man defence; Antonio Conte hasn't looked back since.

Since Chelsea began playing that 3-4-3 formation they have lost twice in all competitions. One was a League Cup loss, that nobody will really mind, but the second was against title rivals Spurs and were it not for that defeat, Conte's team could be out of sight at the top of the Premier League.

Mauricio Pochettino is the only manager of a top six side to have figured out how to beat Chelsea 2.0 and the next to try is the coach who first forced Conte into his successful tactical change.

So how can Arsène Wenger get his team back in the title race?

Adapt to Chelsea's weaknesses

Arsenal are notorious for not adjusting their tactics to their opponents but Wenger must do so for this match. Wenger has been guilty in seasons past of putting a team out and hoping for the best - as we have seen all too often, it doesn't work enough of the time.
