Arsenal have received a major boost as striker Olivier Giroud is back in training following his recovery from a fractured tibia, he suffered during Arsenal's 2-2 draw against Everton on August 23.

"Further to a successful rehabilitation programme so far, Olivier Giroud is back in training," a statement on Arsenal's official website read.

The French striker, who had surgery to fix the broken tibia four days after his injury has been out of action for almost three months. This is welcome news for Arsene Wenger, who has had to rely completely on Danny Welbeck during this period.

Welbeck has made a good start to his Arsenal career, but has struggled to find the back of the net in recent games with the Gunners relying heavily on Alexis Sanchez to bail them out of difficult situations. However, that has not been enough in recent games after they went down 2-1 to Swansea City despite the Chilean's heroics.

Giroud was expected to be out for much longer, but as Wenger had confirmed earlier that his recovery is ahead of schedule and it is expected that the striker will return to action before the hectic Christmas schedule begins.

However, the north London club have not put a specific timeframe on the former Montpellier striker's return to the first-team, and considering the time the French manager took to ease Theo Walcott in, one should expect Wenger to take his time with the French international as well.

This will rule out Giroud's participation against Manchester United following the international break, but he should play a part soon enough.

Meanwhile, Arsenal have denied reports which suggested midfielder Abou Diaby had suffered another setback on his road to recovery and will be out for a further three months.

According to the Standard, the midfielder is on course to regaining full fitness but is still not fully ready to play competitive football on a regular basis.

Diaby has featured for Arsenal only once this season, when he completed 60 minutes for the Gunners against Southampton in the Capital One Cup. He has also featured for the U21's as he continues to build fitness with the club's medical staff.
