Adrian’s error against Atletico underlined Liverpool’s need to sign another goalkeeper to cover for Alisson, says journalist David Maddock on Sunday Supplement.

Adrian’s error proved costly. A back-up ‘keeper, to challenge Alisson – who was also sidelined earlier this season with a calf problem – will be a priority transfer for Liverpool when the window opens again, believes Maddock, the Daily Mirror’s northern football correspondent.

“Simeone was going crazy because he knew his team was getting absolutely destroyed,” said Maddock, “And they were destroyed.

“Liverpool had 37 shots on goal which is a Premier League side against a non-league side sort of level. Had they scored seven or eight it would have been perfectly justified. They scored two, were in the lead and then the ‘keeper just chucked one in. It was the worst mistake you’ll ever see.

“He was garbage. To be fair, he’s been an accident waiting to happen for the last few weeks. I kind of thought if Liverpool were to go out it would be because Alisson was injured and that’s the way it proved.

“Liverpool did plenty enough to win the game – probably enough to win four games – and then fate turned against them.

“[Adrian] did alright earlier in the season but he was a bit mixed even then and I think Klopp kind of knows that’s been a weakness of Liverpool. Alisson getting injured twice in a season, that’s not good actually.

“I think you’ll find Liverpool, whenever they do go out to sign players, if it’s this summer, they’ll go out and sign a ‘keeper, I’m pretty sure about that.”
