Arsenal are likely to be without Per Mertesacker for their Champions League opener against Dinamo Zagreb after the defender was involved in a minor road traffic accident on Monday.
Jack Wilshere and Danny Welbeck are also out.
But Theo Walcott will be hoping to be involved at the same venue where he scored a hat-trick for England in 2008.
Dinamo are back in the Champions League after two year away, and on a 41-game unbeaten streak in all competitions.

The Gunners can expect a stern test against the Croatian champions on Wednesday, but defender Nacho Monreal believes they have enough experience to cope.
"Everywhere you play, the atmosphere is massive, it does not matter if it is Champions League or if it is Premier League," the Spain full-back said.
"We are used to it and we have the experience to cope with playing in big away matches.
"It is more psychological than it is physical, but we are accustomed to it, so it won't affect us."
