Arsenal duo set to return from injuries in cup clash

Francis Coquelin: Centre-back?
Francis Coquelin and Tomas Rosicky could return for Arsenal in Saturday’s FA Cup tie against Burnley, Arsene Wenger has confirmed.
Coquelin has been out since suffering a knee injury against West Brom in November, while Rosicky is yet to play at all this season.
Both players have returned to training in recent weeks, though, and Wenger will consider both for selection this weekend.
Wenger told Arsenal’s official website: “[Per] Mertesacker is out because of the red card,but everybody else is available, apart from Jack Wilshere and Santi Cazorla.
“After that it is just a question of selection and decision-making, that is the key.
“Francis is available to play now because he has passed two weeks of full training.
“Tomas is also available for selection.”
On Arsenal’s remaining injured players, Wilshere, Cazorla and Danny Welbeck, Wenger added: “Jack and Santi are progressing well, but they are at least a few weeks away.
“Danny Welbeck is not completely ready but he is not far. He needs a game or two because he’s been out since last April.
“The Stoke [under-21] game is too soon because he only had one session with the team, and that is too short.”
