Arsene Wenger has revealed that Hector Bellerin will be fit for the trip to the Hawthorns on Saturday, however, midfield duo Alex Oxlade-Chamberlain and Aaron Ramsey remain sidelined.
The Spanish right-back missed the Gunners last two outings against Sp*rs and Bayern Munich with a groin problem, but appears to have recovered during the two-week Interlull.
Chamberlain and Ramsey, both suffering from hamstring problems picked up in October, had been tipped to face West Brom but will not be risked.
“Ramsey should be available on Monday, and maybe Chamberlain as well,” said Wenger.
Theo Walcott, Jack Wilshere, Danny Welbeck and Tomas Rosicky, are still out.
“Walcott is doing well, he could be a bit ahead of schedule but still you count a few weeks more while Rosicky, Wilshere, Welbeck will be later.”
