Mikel Arteta has admitted Arsenal made a mistake with their goalkeeper signing last summer.
The Gunners recruited Iceland international Runar Alex Runarsson from Dijon after Emiliano Martinez departed for Aston Villa towards the end of the window.
Runarsson, 24, has struggled when he has filled in for Bernd Leno and is now expected to leave on loan.
And Arteta says the club will now look at signing another goalkeeper this month.
"There is nothing there yet [regarding Runarsson]," the Spaniard told a press conference on Monday.
"We are assessing what is going to happen with the three positions, the discussions we had in the summer with Edu and the club were a little bit different to what actually happened because of the transfer window and the situation that developed with Emi at the end of the day.
"We didn't have much time to do what we really wanted to do and we decided to assess the situation now in this window, which is what we are trying to do, and we will make a decision about how we want to move forward in those three positions in the goalkeeping area."
