The Belgian goalkeeper has been the centre of intense speculation this season after some indifferent performances for the Anfield side.
Mignolet kept more clean sheets in the Premier League than any other goalkeeper in 2015 but has still come in for criticism from fans and pundits for some shaky displays between the sticks.
His back-up Adam Bogdan did not fare much better when thrust into the first team recently with his errors in the 3-0 defeat to Watford prompting speculation that Reds boss Jurgen Klopp could be in the market for a new keeper, as reported by the likes of the Daily Star.
Mignolet was powerless to stop West Ham from cruising to a deserved 2-0 win over Liverpool to kick off the new year.
But he was criticised by live radio commentators for his performance regardless and one of the Hammers' former 'keepers used it as a chance to speak up for the under pressure Belgian.
'He is the least of their worries'
Posting on Twitter, Walker, who was a real fans' favourite during his five years with the Hammers, said: "Great win for the Hammers. Liverpool bang average, all I heard on radio is Mignolet is poor... looks the least of their worries to me!"

Mignolet has received the public backing of Klopp on more than one occasion in recent weeks.
The German coach says he is happy with his number one and even suggested Mignolet has been offered an extension to his present deal which still has two and a half years to run.
If anything Mignolet kept the score down
While there is no getting away from the fact some of the Belgian's performances have cost his side dear, there was nothing he could do to stop two fantastic headed goals at Upton Park.
Michail Antonio's diving header and Andy Carroll's second half goal were both powerful and well placed efforts which had more to do with Liverpool's failure to stop quality crosses coming in than anything else.
If anything Mignolet had big hand in keeping the score down as he made a number of important saves from Antonio, Manuel Lanzini, Carroll, Aaron Cresswell and Cheikhou Kouyate to stop the Hammers running riot.
