Liverpool manager Jurgen Klopp has admitted that he will need to wrap goalkeeper Adrian up in cotton wool, while Alisson recovers from the calf injury he picked up on the opening day of the season.
The Brazilian number one, who won the Copa America this summer, was taken off just before half-time against Norwich, falling awkwardly after attempting to clear the ball in front of the Kop end.
He was replaced in goal by summer signing Adrian, with the Spaniard only arriving to replace Simon Mignolet at Anfield just days before the new campaign began.
The former West Ham stopper, who was released in the summer after falling behind Lukasz Fabianski in the Hammers pecking order, now faces an extended run in goal for Liverpool - and Klopp has admitted to Liverpool's official website that he must protect Adrian and ensure that he is well looked after.
