Before every Arsenal fixture, we’ll bring you a Scouting Report on the Gunners’ next opponents.
Former Arsenal midfielder Stewart Robson will give his pre-match view and you can get his post-match verdict in our Talking Tactics feature on Arsenal Player.
Arsène Wenger and his side travel to the DW Stadium to face Wigan Athletic in the Premier League on Saturday so, to find out more, we also asked journalist Paul Kendrick for his thoughts and analysis.
"Roberto Martinez has continually changed his team from week to week but of those who started last week, the pace of Moses is the biggest threat to Arsenal.
"It is widely accepted that the Wigan boss is a good coach but his team lack cohesion at the back and a lack of guile in their attacking play. If WIgan are to survive they will need to have a more structured game plan.
PAUL KENDRICK, WIGAN EVENING POST
"They normally play 4-5-1, that's the way Roberto Martinez has always played. In the last couple of games he's changed it slightly to put an extra man in midfield with three defenders - sometimes there's as many as six in midfield with just the one up front.
"He's just started to tinker with the formation and we're undefeated in the last two, so I'd imagine he'll carry on with that at the weekend.
"When Wigan haven't got the ball the back three becomes a back five and when they do you see Ronnie Stam and David Jones pushing forward. They'll probably try and pack the midfield, try and dominate there and get forward at every opportunity.
"The last couple of games have been quite good. They conceded three goals against Blackburn but after that one inside the first minute there was another freak goal from a corner. The other was a last-minute penalty.
"Against Sunderland there was a slight error from a goalkeeping perspective but other than that they've been quite tight. That's more surprising when you consider than Antolin Alcaraz has been suspended for two games, which we did think was going to be a big miss.
"Obviously Arsenal were struggling at the beginning of the season but in recent weeks it looks like they've picked up and they look as formidable as ever. I don't think it's necessarily a case of exploiting any perceived weaknesses, I don't think there's too many in that Arsenal team.
"I think for Wigan they will just try and do what they always have done against Arsenal. They'll concentrate on what they do well, try and get Victor Moses on the ball and pack the midfield to get James McCarthy and Mohamed Diame involved and support the strikers.
"Martinez made five changes for the Blackburn game and really shook things up. McCarthy, up to that point, hadn't had a great season and has found himself on the bench fairly often. But in the last couple of games he's been really good, back to his best. He'll be a key man if Wigan are to do anything this weekend.
"I think after two games unbeaten, Wigan will just try and keep it going. I don't think you'll find any WIgan fans who wouldn't take a point, but as you saw two years ago with the 3-2 victory, anything's possible."
