The Belgian is very much the number one goalkeeper at Anfield, having kept Adam Bogdan at bay this season.
He has often been a target for criticism, though, since his move in 2013, with him famously being dropped by Brendan Rodgers last season.
He bounced back quickly, and strongly, from that disappointment, but was once again criticised last week following a blunder in the 2-1 win over Bordeaux.
That led to many questioning whether the club should replace him, but Hamann says that shouldn’t be a debate.
“He’s a very talented goalkeeper,” he told talkSPORT.
“The way he responded last year, and the way he’s kept goal this year for large parts, has been exceptional. He has the most clean sheets in the Premier League in 2015.
“I wouldn’t swap him for any goalkeeper in the Premier League, other than David de Gea and Thibaut Courtois, he’s that good a goalkeeper. He’s still young and he can still improve.”
Mignolet’s impressive record across 2015 clearly shows that he is a very capable goalkeeper, despite what the detractors may say.
Stats from this season alone show he is still up there in the clean sheet charts, with only Manchester City’s Joe Hart and Arsenal’s Petr Cech having kept more than him so far.
He is level with the likes of Tottenham Hotspur’s Hugo Lloris and Stoke City’s Jack Butland, both of whom have been lauded for their performances.
Stats like those suggest the Belgian is perhaps deserving of more praise than he currently receives.
