Arsene Wenger says Arsenal midfielder Santi Cazorla could be back in full training next week, while Jack Wilshere will continue his return to fitness by playing with the under-21s again Thursday.
Cazorla has been out since November with a serious knee injury and his recovery has been hampered by an Achilles problem.
But Wenger said Thursday that both the Spaniard and Alex Oxlade-Chamberlain could be back in training soon.
"Next week they will be back maybe, they are not back in full training yet. They are still on fitness work," Wenger told Arsenal's official website.
Wilshere played his first game of the season with the U21s last Friday after recovering from a fractured ankle and will make another start in Thursday's game at Swansea.
Tomas Rosicky will also play as he continues his recovery process from a thigh injury.
Both Wilshere and Rosicky are hoping to return to the first team before the end of the season to prove their fitness ahead of this summer's European Championship.
"Jack and Tomas are playing today for the under-21s. They have had no reaction from last Friday's game and they look alright," Wenger said.
Oxlade-Chamberlain injured his knee against Barcelona in February and is also facing a race against time to be considered for Roy Hodgson's England squad.
Wenger said there were no other injuries to the squad following Saturday's 3-3 draw at West Ham.
The Gunners play at home against Crystal Palace on Sunday hoping to keep alive their slim chances of catching Premier League leaders Leicester.
