Liverpool manager Jurgen Klopp has been told to sign Jack Butland from Stoke City to replace Adrian by a former England number one.
Adrian performed poorly against Aston Villa on Sunday, playing a stray pass in the fourth minute to allow striker Ollie Watkins to give the underdogs the lead.
The Spanish keeper went on to concede six more goals in the match, making it Klopp’s biggest ever defeat as a manager.
Adrian is currently in the first team following an injury to number one Alisson, who could be out until late November.
Following the 7-2 humiliation, Liverpool have been told to sign out-of-favour Stoke keeper Butland by former England shot-stopper Paul Robinson.
Speaking to Football Insider, Robinson said: “If Alisson is going to be out for that length of time Liverpool are going to have to look at it.
“While the domestic window is still open we may see Liverpool do some business. There is a lot of good goalkeepers that are not playing football right now.
“I can see Liverpool signing the likes of Jack Butland on a short-term deal. They need somebody like that. A player that has the experience of handling big games. Somebody of that ilk.”
The domestic transfer window is open until Friday 16th October, meaning the Reds have over a week to look at potential keepers.
Butland could be the best option for Klopp due to his current status at Stoke. The 27-year-old has declared his intent to leave the club when his contract expires next summer, which has led to his first team opportunities being reduced.
Butland is a decent shot-stopper with both Premier League and international experience. He’s featured in the Prem 77 times for his current club and has nine caps for England.
One potential stumbling block for Liverpool would be interest from other clubs. Southampton have been linked with a swap deal for Butland, which would involve Angus Gunn moving up north.
