Wenger reverted to the patchwork approach he has taken to European team selections this season, Mathieu Debuchy playing for the first time in almost a year, while Mohamed Elneny featured alongside the Frenchman in a back three and Reiss Nelson, scorer of six goals in five Under-23 games this season, was deployed at wing-back.
The game was rather tiresome.
Richmond Boakye hit the post for the hosts in the first half.
Arsenal improved in the second half which wasn't hard given how poor they were in the first. Arsenal had a great chance to start the half, but Giroud couldn't finish off the great pass from Walcott.
A number of first team players have not travelled for the fixture, but Wenger does select the experienced Petr Cech in goal. Hopefully then, most of the action will be at the other end and with a strong attack of Walcott and Giroud with Jack Wilshere to create chances we should have plenty of potency up front. They found success playing quick one-twos with Giroud, but were still unable to break the tough Red Star defense.
"Overall, the spirit we showed was remarkable, fighting together in a game that was very physical". That's why he scores at moments you didn't expect him to score.
Olivier Giroud scored a breathtaking goal in the late stages, as Arsenal claimed a 1-0 win over Red Star Belgrade, in their Europa League Group H tie on Thursday night. You have to love that big handsome frenchman.
The win means that Arsenal have moved 5 points clear at the top of the group, ahead of tonight's opponents and BATE Borisov with Koln at the foot of the table.
And former United star Keane believes Arsenal are struggling to keep up with their Premier League rivals.
