Arsenal manager Arsene Wenger has revealed that a slight setback was the reason for Alex Oxlade-Chamberlain missing the trip to the Hawthorns to face West Bromwich Albion on Saturday (21 November). The England international has been sidelined since suffering a hamstring injury during the Gunners' 3-1 loss at the hands of Sheffield Wednesday in the League Cup late last month.

Oxlade-Chamberlain was penciled in to return to the side following the recently concluded international break, with the player himself sharing a video of him training with the rest of the squad. Wenger, however, despite the latest setback, is confident of having the midfielder back for the clash against Norwich City on 29 November.

Meanwhile, Aaron Ramsey, who has also been out since suffering a hamstring injury during Arsenal's win over Bayern Munich on 21 October is expected to return for the north London club's midweek Champions League clash against Dinamo Zagreb.

Theo Walcott, on the other hand, is still two weeks away after suffering a calf strain during the game against the Owls, but Wenger admitted that he is ahead of schedule. The French manager will be glad to see his team's injury crisis on the mend ahead of the busy period, which will see them play some crucial matches in the Premier League and Champions League.

"He had a slight little setback on Monday but we checked by scan and there is nothing wrong but he is still a fraction short for Saturday," Wenger said, as quoted by ESPN FC.

"Ramsey will be back in full training on Monday and can play on Tuesday and Chamberlain I think against Norwich. Theo is ahead of schedule at the moment but he is still two weeks away," the Gunners boss added.
