Arsenal Striker Olivier Giroud Ruled Out of Borussia Dortmund Clash Following Admin Error

Arsenal striker Olivier Giroud is reportedly set to miss the Champions League clash against Borussia Dortmund after the Gunners failed to register his name in the 25-man squad list for the group stages of the competition.

According to the Daily Mail, Arsene Wenger was supposed to submit the 25-man squad list by August 31 and with the French striker fracturing his left tibia on August 23, he was left out of the squad after doctors diagnosed that the injury would keep him out until 2015.

However, the former Montpellier forward made a quicker than expected recovery and has returned to action a whole month ahead of schedule. He came on as a second half substitute and scored a goal in Arsenal's 1-2 loss at home against Manchester United on Saturday.

The north London club need one point from their remaining two games in the Champions League group stages to qualify for the next round and face Dortmund at home and Galatasaray away in the last game.

Arsenal are allowed to make three changes to their original squad list after the first stage of the competition, therefore allowing the Frenchman to take part in the rest of the competition if Wenger's men make it through.

Gunners star Jack Wilshere is a doubt for the game after he picked up an ankle injury and so is goalkeeper Wojciech Szczesny, who injured his hip following a collision with teammate Kieran Gibbs.

The Gunners boss will again have to depend on Danny Welbeck to lead the line, despite the Englishman struggling to find the back of the net in recent games.

The manager is also yet to give an update on forward Theo Walcott, who only returned recently from a nine-month layoff to pick up a groin problem on international duty.
