Last season's Champions League finalists face either Dinamo Zagreb of Croatia or Lithuanian side Ekrenas -- most likely the former, who took a 4-1 away win in the first leg -- in a third round qualification match in a week's time.

The Gunners face qualification to reach the main group stage as they finished fourth in the Premiership last season.

As well as German goalkeeper Jens Lehmann, who is suspended after being sent off in May's Champions League final defeat to Barcelona, Henry will miss the first leg, Wenger said.

"Jens is suspended and Thierry will be short as well," Wenger said after Arsenal's 8-1 thrashing of Austrian third division side Schwadorf in a pre-season friendly.

"He (Henry) comes back on August 2 so it is very short until August 9."

The team playing the Champions League tie would be very similar to that which defeated Schwadorf, Wenger said, although Czech midfielder Tomas Rosicky and teenage England striker Theo Walcott could also feature.

"Tomas Rosicky is OK," Wenger said. "Theo Walcott is a bit short. He has had a virus so he has not practised well.

"The fittest players will play whether it means Walcott or not I don't know yet."
