Liverpool manager Jurgen Klopp will be “really concerned” by the injury to Alisson, according to Paul Robinson.

The former England number one, speaking exclusively to Football Insider correspondent Dylan Childs, claimed that Adrian’s confidence “has been shot to pieces” and is “spreading through the defence”.

Adrian stood in for the injured Alisson on Sunday night and was criticised for his display in a humiliating 7-2 loss at Aston Villa.

Jurgen Klopp later revealed that Alisson was “likely” to be sidelined for six weeks.

He is set to miss Premier League games against Everton, Sheffield United and West Ham as well as Champions League fixtures against Ajax, FC Midtjylland and Atalanta.

He also face a race to be fit for the trip to Manchester City on 7 November.

When asked by Football Insider for his thoughts on the current goalkeeper situation at Anfield, Robinson said:

“Adrian looked shaky, vulnerable and his save-to-shot ratio had gone right down at the end of last season. His performance at Villa was really poor. You can see that his uncertainty and lack of confidence is spreading through the defence.

“They have Kelleher as their number three but he is only 21-years-old. They let Mignolet and Karius go.

“Jurgen Klopp will be really concerned in that area. Adrian has the experience but his confidence has been shot to pieces and that game the other day is not going to help.

“If Alisson is going to be out for five to six weeks, how long do you leave Adrian in for? He is only in right now because there is no other feasible option.

“It is a big concern for Liverpool because they do not carry a number three like Joe Hart at Spurs, Scott Carson at Manchester City or Sergio Romero at Manchester United.”
