Laurent Koscielny and Alex Oxlade-Chamberlain in contention to make Arsenal returns against West Ham

Arsene Wenger is hopeful of having Laurent Koscielny and Alex Oxlade-Chamberlain back in his Arsenal squad ahead of Sunday's meeting with West Ham United.

France international Koscielny has not featured for the club since the 1-0 win over Southampton on 3 December due to a calf injury.

The defender has also struggled with an Achilles problem this season but is in contention to return to the first team to ease the injury woes that have dogged Arsenal's season.

Oxlade-Chamberlain also has a small chance of featuring at Upton Park having missed the 2-1 win over Queens Park Rangers on Boxing Day.

"[Laurent] Koscielny has a chance, he will have a test tomorrow," Wenger told the club's official website. "He has a little chance. [Alex] Chamberlain has an even smaller chance."

Theo Walcott, who has featured just twice in the last nine months, is also edging closer to full fitness having been an unused substitute on Friday.

"[Walcott] was in the squad on Friday but it was difficult to bring him on when it was tight and we had to defend. He's not far away."

Arsenal's win over QPR saw them move to within a point of fifth placed West Ham while Southampton's win over Crystal Palace saw them move into fourth place.

With Saints hosting the league leaders Chelsea on Sunday, the Gunners could potentially move into fourth place by the end of the weekend should results go their way.

But Wenger doesn't believe the hectic festive period will have little bearing on their campaign.

"I don't give importance to the table at the moment," he said. "There's 20 games to go.

"It's very tight and it's down to consistency now. We know every game now is down to consistency and reproducing the performances. We need to prepare quickly, focus quickly and that is an ability we want to show at West Ham.

"The plan is to sleep well and recover. We want to stay in the game. We'll train on Saturday morning and on Saturday night we go to the hotel. It's very quick and interesting as well."
