Bolton v Arsenal; Reebok Stadium; Premier League; Wednesday, 1st February; 20:00 KO.
Bolton boss Owen Coyle will be without January signing Tim Ream, who has returned to New York in a bid to sort out an ongoing work permit issue.
Loan arrival Ryo Miyaichi is ineligible to play against his parent club, while Marvin Sordell was signed too late to be registered for tonight's game.
Meanwhile, Arsenal have been boosted by the return of Thierry Henry, Bacary Sagna and Mikel Arteta, while Johan Djourou has overcome a groin strain and is available for selection.
Arsene Wenger still has injury concerns at the back with long-term absentees Kieran Gibbs, Carl Jenkinson, Andre Santos and midfielder Abou Diaby all sidelined.
Confidence is key, says Koscielny
Laurent Koscielny will take a cautious approach into tonight's Premier League fixture against Bolton, as Arsenal look to overturn their wretched run of form at the Reebok Stadium.
The 26-year-old defender insists neither he nor his teammates will be taking the Trotters lightly despite their lowly league standing, but is confident of a first win in four attempts against Owen Coyle's men on their own patch.
Bolton upset the odds in last year's corresponding fixture, and Koscielny is hoping to avoid a repeat, as the Gunners look to get their league campaign back on track after a series of disappointing results.
"It was a difficult game like every game in England is," he told Arsenal Player. "You know the whole team wants to win the game.
"We know we will go to Bolton to win it and we must get the three points. It is very important to get that fourth place.
"It is difficult because every team who battles relegation wants to do everything to stay in this league. We know in England that there is a fighting spirit on the pitch, with atmosphere in the stands.
"We know last year that we lost at Bolton, this year we lost at Blackburn and they were difficult, difficult games. But we must go there to win the points."
After a quiet January transfer window for Arsenal, Arsene Wenger has shown he has faith in the players he's got, and fans will hope the frugal Frenchman's confidence will be carried onto the pitch, as the club continues its pursuit of that all-important Champions League place.
