Elliot was in brilliant form for Newcastle as they picked up a 1-0 victory over Bournemouth at the weekend, which lifted them out of the Premier League relegation zone.
Newcastle had been on the back-foot for much of the tie, but Bournemouth’s efforts were not rewarded as a result of Elliot’s goalkeeping masterclass, and Dummett claims that the stopper’s performance has increased confidence levels within the squad.
"It gives you confidence when Rob is pulling off saves like that," he said.
“If he’s doing that for you, you have to do everything you can for him.
“It’s a massive confidence boost for the team when a player is playing like that. It helps you out so much.”
Elliot went into this season as Newcastle’s third choice goalkeeper, but he has grasped his opportunity in their first-team with both hands.
The 29-year-old has come into the team with both Tim Krul and Karl Darlow out injured, and he has made himself virtually undroppable with his performances.
That should stand him in good stead for the future, with Darlow on the verge of returning to fitness.
Darlow was signed to be Newcastle number two, but it would be very harsh on Elliot if Steve McClaren was to drop him, after his recent run of form.
Krul, meanwhile, could be out for the rest of the season – after picking up a very damaging knee injury while on international duty with Holland.
