Arsenal v Swansea preview
Arsenal will have both defender Kieran Gibbs and midfielder Alex Oxlade-Chamberlain available against Swansea on Tuesday night following successful disciplinary appeals to the Football Association.
Defender Laurent Kosielny (calf) misses out, so 19-year-old Spaniard Hector Bellerin, who was on loan at Watford, has been drafted into the squad as cover. Sweden midfielder Kim Kallstrom (back) could feature for the first time since signing in January having been on the bench at Chelsea.
German international Mesut Ozil (hamstring) remains out, midfielder Aaron Ramsey (thigh) is still a couple of weeks away from full fitness, while Jack Wilshere (foot), Theo Walcott and Abou Diaby (both knee) all continue their rehabilitation.
Swansea head coach Garry Monk has reported no fresh injury concerns following his side's 3-2 defeat at Everton.
Given the quick turnaround in fixtures, Monk might opt to start fit-again Spanish striker Michu, who scored twice when Swansea won 2-0 in north London 15 months ago.
Michu, who was sidelined for three months due to an ankle injury, has featured as a substitute in Swansea's last two games against West Brom and Everton.
