Arsenal have no new injury worries ahead of the visit of Barclays Premier League leaders Leicester on Sunday.
Danny Welbeck is close to a return having missed all season with a knee injury but manager Arsene Wenger still expects Jack Wilshere (leg) and Santi Cazorla (knee) to be out for another three to four weeks.
Tomas Rosicky (thigh) is also absent while Wenger will have to decide whether to recall Per Mertesacker or keep Gabriel and Laurent Koscielny as his centre-back partnership for the fourth game in succession.
Provisional squad: Cech, Ospina, Monreal, Gibbs, Koscielny, Gabriel, Mertesacker, Bellerin, Chambers, Ramsey, Elneny, Coquelin, Flamini, Ozil, Oxlade-Chamberlain, Reine-Adelaide, Iwobi, Sanchez, Campbell, Walcott, Welbeck, Giroud.
Midfielder Daniel Amartey must wait for his Leicester debut and will not feature against Arsenal.
The 21-year-old joined from FC Copenhagen in January but is yet to make his bow for the Barclays Premier League leaders but boss Claudio Ranieri expects to have him up to speed to face Norwich next week.
Jeff Schlupp remains sidelined with a hamstring injury which has kept the winger out since the start of December while Matty James is close to a recovery from a long-term knee injury but the Foxes are expected to be unchanged following their 3-1 win at Manchester City last week.
Provisional squad: Schmeichel, Schwarzer, Simpson, Morgan, Wasilewski, Huth, Chilwell, Fuchs, Albrighton, King, Drinkwater, Kante, Inler, Gray, Dyer, Mahrez, Vardy, Ulloa, Okazaki.
