Liverpool must to sell full-back Albert Moreno and goalkeeper Simon Mignolet after both players were at fault during the Capital One Cup final defeat on penalties to Manchester City at Wembley, claims club legend Jamie Carragher. Moreno and Mignolet both made errors in the lead up to City opening the scoring through Fernandinho's strike from a tight angle – and Carragher has lost patience with the duo.

Manuel Pellegrini's side took the lead four minutes after the break when Sergio Aguero fed Fernandinho, who escaped Moreno before firing under the despairing dive of Mignolet. While the Belgium international twice kept out Aguero during the 120 minutes, Moreno endured a torturous afternoon and could have conceded a penalty after felling Aguero.

Both players have been first-choice for Liverpool in their chosen positions this season but their inadequate performances have contributed to Jurgen Klopp failing to dramatically improve the club's fortunes since his arrival. The German boss has steadfastly defended the pair, particularly Mignolet, who was handed a new five-year contract in January.

But Carragher said, according to the Liverpool Echo: "The left-back has to come out of the team. This is not a one-off in terms of the goal. [Jon] Flanagan has come back fit and has to go into the team in midweek, he [Klopp] has to change the left-back.

"Flanagan played left-back when they nearly won the league. He can't be worse than him [Moreno]. The goalkeeper has made some outstanding saves, but just because you make some outstanding saves doesn't mean you should be allowed to concede a goal like that. And that is not just today.

"Going forward for Liverpool, those are two areas Jurgen Klopp has to change in the summer. The goalkeeper may have signed a five-year deal, and he has made some good saves today, but things have to change."

On the opening goal, which was eventually cancelled out by Philippe Coutinho's strike that forced the game into extra time and then penalties – which Liverpool went on to lose 3-1 – Carragher added: "It starts with the left-back Moreno. He splits initially from a goal kick, but now he knows isn't going to receive the ball he has to get back.

"Sergio Aguero is in the right position to pick up the ball because his opposite full-back has gone in to go for a header. And then he (Moreno) doesn't see the run.But that (the goalkeeper) is shocking. You can't score from there."
