The goalkeeper's progress at Liverpool has pleased manager the club's German boss, who hailed his talents as a shot-stopper
Liverpool manager Jurgen Klopp praised Loris Karius and feels he would be proven an "idiot" if the goalkeeper was not a good shot-stopper.
Karius kept a clean sheet as Klopp's side recorded a 2-0 win over Newcastle United in the Premier League on Saturday.
The German goalkeeper has become first choice at Anfield, having arrived from Mainz in 2016.
Klopp said he had been pleased with the progress the 24-year-old Karius has made since joining the club.
