Unai Emery says there is a “possibility” the club could sign two new players before Thursday’s deadline.
His words, “This transfer window is not easy,” the Spaniard, 47, said.
“The message is the club is working on different players and the possibility if it can be good for us.
“We are looking at two different players and the possibility they can come. If they aren’t coming to help us like we want, I prefer they don’t come.”
Sokratis has been ruled out until the end of February with an ankle injury while Koscielny is “being reviewed on a daily basis” after bruising his jaw.
The Gunners are also without full-back Hector Bellerin, who has been sidelined for the rest of the season with a ruptured anterior cruciate ligament.
“We have enough players, centre-backs, in the squad,” Emery said.
“Only we’re having a lot of injuries and a lot in this position.
“If we can bring another player and when all the players want to play, we can have a lot of trouble in the future.”
