Theo Walcott Arsenal

Arsenal received some good news on injuries on Monday -- and it is about time, considering the amount of problems suffered on the fitness front this season – with Theo Walcott and Serge Gnabry returning to training from long-term problems.

Walcott has been out of action for Arsenal since January, when he suffered a cruciate knee ligament injury in the FA Cup win over Tottenham.

Arsenal missed the speedy forward sorely, as there is no better player at the club to make those runs in behind the defence. Walcott, of late, also has a penchant for goals as well as assists, and if the England international can return to full fitness, it will bode well for the Gunners.

Walcott posted a message on Twitter announcing his return to training. "First full training session after 9 months - feeling good!!" the 25-year-old wrote.

The Arsenal man also posted a picture on Instagram of him in action in training, with Arsene Wenger, no doubt, heaving a sigh of relief at that sight.

Gnabry's return will also be welcome as the German gives the manager another option out wide, with the youngster a pretty good option as an impact substitute when Arsenal are in need of a goal.

While it is unlikely that Walcott will start Arsenal's next game in the English Premier League – against Hull City on Saturday -- both Walcott and Gnabry could make the bench.

There was more pleasing news for Arsenal on the injury front, with Wenger revealing striker Olivier Giroud could make a return sooner than expected. Giroud was ruled out until the New Year after injuring his ankle in August.

"Olivier Giroud is recovering very well," Wenger revealed on Bein Sports. "I believe he is ahead of schedule in terms of rehabilitation. The operation went perfectly."

The return of Giroud will pose Wenger some selection problems, with Danny Welbeck, the deadline day signing from Manchester United, doing pretty well at the moment as the lone striker up front.

However, the Arsenal manager believes Giroud and the versatile Welbeck are capable of playing together.

"Welbeck and Giroud can play together in the centre or separately," added Wenger.

"Welbeck also played on the sides for Manchester United. Welbeck played in the same team with Rooney and [Robin] Van Persie. He can play down the sides."
