Arsenal are set to welcome back Santi Cazorla for the Premier League visit of Norwich City while Theo Walcott and Bacary Sagna are in line for a return against Borussia Dortmund in the Champions League, according to

Cazorla hasn't featured for The Gunners since the win over Tottenham Hotspur at the beginning of September and has missed the last seven games with an ankle problem.

After abdominal surgery, Walcott has been out since the victory against Stoke City and was unavailable for England's World Cup qualifiers against Montenegro and Poland.

Sagna suffered a hamstring injury in the Champions League win over Napoli which forced Carl Jenkinson into deputising in the 1-1 draw with West Bromwich Albion.

The Spaniard Cazorla is expected to be available for the visit of Norwich this weekend, Arsenal's first game after the international break. Walcott and Sagna meanwhile are both likely to be in contention to play against Borussia Dortmund in the Champions League.

The duo will return to training this week and will be regularly assessed before their fitness is confirmed.

With Arsenal top of the Premier League after seven games the news that three of his most important players are set to return from injury is a massive boost to manager Arsene Wenger who has operated under severe restrictions this season.

Several first team players have suffered long-term injury including Abou Diaby and Alex Oxlade-Chamberlain - neither of whom are expected to play before the New Year, while Lukas Podoski suffered a hamstring tear early in the campaign.

Nevertheless, following the opening day defeat to Aston Villa, Arsenal strung together ten successive wins in all competitions to silence their critics. The draw with West Brom ended the run but keepts Arsenal top of the Premier League.

With pre-season title favourites Manchester City, Chelsea and Manchester United all suffering early season problems, Arsenal and Liverpool, who are level on points, are the early-pace setters laying the foundations for one of the most open races for the title in decades.
