Liverpool manager Jurgen Klopp said keeper Alisson would hopefully "learn from his mistake" after gifting Leicester City a goal in the visitors' 2-1 win at the King Power Stadium on Saturday.
With Liverpool two up and apparently heading for an easy win in the Premier League game, the Brazilian refused to take the easy option of just clearing his lines when put under pressure by a poor Virgil van Dyke backpass after the break.
Instead Alisson tried to beat Kelechi Iheanacho with a step over but was robbed of the ball by the striker who centred for Algerian Rachid Ghezzal to find an empty net and spark a Leicester fightback.
