Arsenal may be without some major names for their trip to Zagreb but, according to Arsène Wenger, there is no need for pessimism.
The likes of Philippe Senderos (shoulder), Freddie Ljungberg (ankle), Gael Clichy (foot) and Abou Diaby (ankle) will miss the game in the Croatian capital through injury.
Thierry Henry, Jens Lehmann and Theo Walcott have not been on the treatment table but they are lacking match fitness after their World Cup exertions.
It means the travelling party for the Champions League third qualification round first leg tie will be based on the one which beat AZ Alkmaar 3-0 in a friendly on Friday.
"I can not say the starting line-up but this 18 could go," said Wenger after that game. "You can add Tomas Rosicky so one will come out.
"Theo Walcott is not ready. He had a virus so he is a little bit behind physically. He will not be involved on Tuesday. He is in the group with Thierry Henry at the moment.
"We know Zagreb is a good team but we know we can beat them. We are a little bit handicapped physically so we want to be intelligent but also we want to go there and score a goal. They have a classical advantage after the World Cup. We had 16 players there.
"But we know for us it is a good opportunity to get into the group stage. We are very aware of the importance of this game and we are confident. We went to Ajax without Thierry Henry last year and managed to make a result. We have to think that in some games that Thierry will not play.
"As well we have just played the final of the Champions League with a very young team. For me, enough players will be sharp on Tuesday. Then we have 14 days to prepare for the return leg. Tuesday is a big game and we will go in to it with a confident attitude."
