The Wales international will be back from a long-term lay-off on Sunday and Nacho Monreal is also fit, but the Arsenal boss has injury concerns over Kieran Gibbs and Serge GnabryAaron Ramsey will return to the Arsenal squad to face Everton at Goodison Park on Sunday, Arsene Wenger has confirmed.
The midfielder was enjoying a rich vein of form this season, before suffering a thigh injury in the Boxing Day victory over West Ham.
Arsene Wenger admitted Ramsey's return is a welcome boost for his side, who have seen their title challenge slip away in recent weeks and now face real competition from the Toffees for the fourth Champions League spot.
"He drives the team forward and he is a box-to-box player. It's good to have him back," Wenger told reporters.
Ramsey bagged eight goals in 18 Premier League appearances before succumbing to injury and will hope to pick up where he left off to help the out-of-form Gunners, who have won just three of their last 10 top-flight outings.
Full-back Nacho Monreal is also available for Sunday's crucial clash, but Kieran Gibbs is struggling with an ankle problem, while Serge Gnabry has a knee injury.
