Wigan v Arsenal preview

Arsenal report no fresh problems ahead of Saturday's Premier League game at injury-hit Wigan, which can be seen live on Sky Sports 3HD.

Last weekend's 2-1 defeat at Norwich proved costly for Wigan, with midfielder James McCarthy and centre-back Adrian Lopez picking up injuries.

Lopez could be missing for up to 10 weeks with a hamstring tear, which is a major blow for boss Roberto Martinez.

He joins Ben Watson (broken leg), Ryo Miyaichi (ankle) and Albert Crusat (knee) on the long-term injured list.

But Arsenal have no such problems and Theo Walcott could again be preferred in a central striker's role ahead of Olivier Giroud after scoring in Monday's 5-2 win at Reading.

Full-back Andre Santos (stomach muscle) and midfielder Abou Diaby (thigh) continue their rehabilitation.
