Arsenal will be without Wojciech Szczesny for around six weeks after the goalkeeper dislocated his finger during Tuesday’s Champions League defeat to Barcelona.
Manuel Almunia replaced Szczesny, but the injury has left Arsenal short of goalkeeping cover.
They are already without Lukasz Fabianski and Vito Mannone and are hoping to arrange emergency loan signing.
“We need an experienced goalkeeper as cover for Almunia,” said Arsenal manager Arsene Wenger.
“We can call Mannone back from Hull, but he is not available,” Wenger added. “We have Wojciech out. We have Fabianski out for the rest of the season. We absolutely need some cover in goal.”
Almunia, who was tipped to leave Arsenal in January, now finds himself as Wenger’s number one.
“He is very professional, has a very dignified attitude and overall he has done very well,” the Arsenal boss said.
“Yes, he has done quite well when he came on against Barcelona – he was quite busy in the final part of the game and he did very well.”
“When I took Jens Lehmann out, who had made only one mistake, and put Almunia in, Lehmann came in the next day and fought even harder. That’s what I believe our job is about.”
