Napoli goalkeeper Pepe Reina insists Loris Karius will prove himself at Liverpool.
Karius was once again heavily criticised after conceding Nathan Ake's 94th-minute winner in last weekend's defeat to Bournemouth.
But former Liverpool No1 Reina told ITV: "I think he doesn't need any encouragement.
"I think he's a brilliant goalkeeper who is doing really well."
He added: "It's a team, you know, that also at times has to do better for the goalkeeper."
