The Belgium international put pen to paper on a new five-year deal on Monday evening despite recent criticism of the shot stopper.
What this deal for Mignolet does show however is that Jurgen Klopp has belief in him
Klopp has been linked with a move for Barcelona goalkeeper Marc-André ter Stegen and Paris Saint-Germain goalkeeper Salvatore Sirigu in recent weeks.
While Aldridge says Mignolet’s new long-term contract highlights Klopp’s faith in the Belgian, the former Liverpool striker is still tipping the German to sign a new shot stopper in the summer transfer window.
Aldridge told Liverpool Echo: “Simon Mignolet has signed a new contract which commits his future to Liverpool for the next five years. As a shot-stopper he’s tremendous and he’s working hard on the other elements of his game.
“However I don’t think this news will stop Jurgen Klopp looking to bring in another keeper to battle for the number one position in the summer.
“When they brought Adam Bogdan in I thought he would be really good for the club. But what happened at Watford has really hampered him.
“The manager will probably go and get a keeper to fight Mignolet this summer for first choice.
“Danny Ward could be that man eventually but he’s probably still a bit young at this stage. He’s been absolutely brilliant at Aberdeen though in the Scottish Premier League and he’s one for the future.
“What this deal for Mignolet does show however is that Jurgen Klopp has belief in him.”
Mignolet was powerless to prevent Wayne Rooney scoring a 78th-minute winner in Manchester United’s 1-0 victory over Liverpool at Anfield on Sunday afternoon.
The 27-year-old goalkeeper kept more clean sheets than any other Premier League goalkeeper in 2015.
The Belgian moved to Liverpool in a £9m deal from Sunderland in 2013.
