Arsenal manager Arsene Wenger has confirmed goalkeeper Petr Cech will miss games against Hull City, West Bromwich Albion, Barcelona and Everton this month.
Reserve goalkeeper David Ospina was outstanding against Tottenham Hotspur at White Hart Lane and will continue in goal for the Gunners.
Defender Laurent Koscielny will also miss today's game against Hull City but is expected to be on the bench on Saturday.
"We lose [Francis] Coquelin from his bad tackle on Saturday and everyone else looks available," Wenger told reporters.
"I have to see how everybody has recovered today but overall we should have the same squad that went to Tottenham plus Alex Iwobi will certainly be added to the squad.
"Petr's [Cech's] scans were better than expected, but it will still be four weeks for him. So after the international break.
"Laurent [Koscielny] will be short for Hull.
"He has a chance to be available for the weekend [against West Bromwich Albion], but I think even for then he will be short."
