The Hammers star, on loan for the season from Manchester City, started in England’s latest World Cup qualifier away in Malta – and will be looking to retain his place against Slovakia tonight.
The England international has had to leave his parent club to find game time two seasons in a row – and Shilton believes that works against him.
The goalkeeping legend also claims that both Everton’s Jordan Pickford and Stoke City’s Jack Butland will be better players than Hart – and they need to start being given more game time.
Speaking in the Daily Mail, Shilton said: “Joe [Hart] is what he is and until now he hasn’t been challenged for his place with England. He’s a good goalkeeper, like Tom Heaton, but nothing more than that. And now his place should be under serious threat.
“He was very lucky to keep his place in Malta, where he had little to do. I expect he will have more action tonight against Slovakia when his performance will come under scrutiny.
“He needs a clean sheet, because he has Jack Butland breathing down his neck. And Jordan Pickford, too, although the new Everton goalkeeper is currently injured.
“We need to see both in action for the national team before the World Cup. If you are not in the team, then you are not even being given the chance to make judgments and eliminate errors.
“Both can become better goalkeepers than Hart. I am excited by the pair of them and they need to push each other to become better and better.”
