Liverpool manager Jurgen Klopp expects the club to sign Andy Lonergan before Wednesday's European Super Cup against Chelsea.
The Reds have lost number one goalkeeper Alisson after he sustained a calf injury in Friday's win over Norwich City.
With Klopp's third-choice keeper Caoimhin Kelleher also injured, Lonergan will be signed as a free agent soon.
"The situation was even more difficult a few weeks ago because of injuries, but Caoimhin Kelleher is now in his final steps for being completely back," Klopp told Liverpool's official website.
"He's training only [for] five days or so, catching balls and all that stuff, it looks all good but of course we have to find a solution in the short term and that will be, if nothing happens from now to then, Andy Lonergan.
"He was in with us, he's a brilliant character, a really nice lad and helped us a lot in the pre-season and now we decided to work together with him.
"So that's a very experienced solution but in the moment when Caoimhin is back then obviously Adrian is No.1, Caoimhin probably No.2 but we have to see how then he can have some games with the U23s or U21s [so] that he gets match practice as well.
"We have to see how that works but that's then how we cover that situation."
