Theo Walcott's return to the Arsenal setup will act as a major boost to the Gunners' title chances.
The English international has been out of action for the north London outfit since he scored in Arsenal's Champions League win against French outfit Marseille in mid September.
And, despite Arsenal still looking strong without the 24-year-old, they will be further improved with him in the squad. Walcott had arguably his finest season in the last campaign for the Emirates outfit and started to show the consistency we've all been waiting for him to produce.
He started this season in fairly decent form too and now he will come into a side looking to bounce back after a second league defeat of the season. And as Arsenal take on Walcott's former side Southampton this weekend, he can have a major influence in the game, should he come on.
With Saints' high pressing game, Walcott can act as an outlet and run in behind their back four. That's what, perhaps, they were missing against Manchester United.
The Gunners possess some of the greatest creative players in the world, with the likes of Mesut Ozil, Jack Wilshere and Santi Cazorla starring for the Emirates outfit. But that added bit of pace will most certainly give Arsene Wenger another option as the Gunners look to continue their title pursuit.
A lot has been made of the importance of striker Olivier Giroud to the Gunners' side and even more has been made out of the lack of cover for the Frenchman. Of course the Arsenal boss can turn to Nicklas Bendtner, but there are not many Premier League defenders that would have sleepless nights over the Dane.
Walcott, on the other hand, can take some of the pressure off Giroud. The winger turn forward has the ability to create and score goals and is always up for the challenge of proving his worth up top.
There's no doubt that the English international can do a job for the Gunners as a striker and as the season goes on, Walcott will be handed more opportunities in an advanced role.
He's proven on occasions that he is a world-class player and Arsenal fans will be hoping he comes back refreshed and determined to contribute to the on going title charge at the Emirates.
