The 27-year-old shot stopper signed a new five-and-a-half year deal with the Merseyside outfit last Monday despite an error-strewn season at Anfield.
Liverpool manager Jurgen Klopp has been linked with a move for a goalkeeper in the January transfer window as he looks to put a stop to the club’s poor record at set-pieces.
Speaking to BT Sport on Saturday afternoon, Hoddle appeared to question Liverpool’s decision to secure Mignolet’s long-term future at the 18-time English champions.
“It is immaterial. Someone else will come in at some stage anyway,” Hoddle said. “Will he prove himself as a better and better goalkeeper over the next five years? I’m not so sure. I think he is at his best now.
“I don’t see him getting any better. He is still a very good goalkeeper. Every successful team needs that spine. Is he a major part of the spine?”
Liverpool have conceded 32 goals in 23 Premier League games so far this season, which includes four against Norwich City in Saturday’s 5-4 victory at Carrow Road.
Mignolet, who is facing competition from Adam Bogdan and Danny Jones for a starting spot, moved to 18-time English champions Liverpool from Sunderland in a £9m deal in 2013.
The Belgian goalkeeper has made 121 appearances for Liverpool over two-and-a-half seasons at the Merseyside outfit.
