Arsène Wenger has one defender out and one defender back for the Champions League qualifier with Sparta Prague on Wednesday night.
Bacary Sagna is sidelined after injuring his lower back in Saturday's 1-0 win over Manchester City.

Philippe Senderos was named in the side for that game but tweaked his ankle in the warm-up. As it turned out, the problem was not serious and the Swiss centre half is available against the Czech champions.
Apart from that switch, Arsène Wenger has the same squad available.
"The injuries are Eboue (ankle), Gallas (groin) and Lehmann (Achilles)," said the Frenchman at Tuesday's press conference. "Sagna is injured too with a kick in the back but he should return for Portsmouth on Sunday. Senderos is back in the squad."
