Jak Alnwick has told Newcastle United manager Alan Pardew that he has the confidence and ability to cover for the club's goalkeeping crisis through December.
The third-choice goalkeeper came off the bench at half time of Saturday's match against Chelsea after Rob Elliot picked up an injury in the first half, and helped the 10-man Magpies to hold on for a 2-1 win.
Alnwick has said that he is ready to feature in forthcoming matches against Arsenal, Tottenham Hotspur and Sunderland this month.
"There are big games coming up, however, as a third choice goalkeeper, this is what I am here to do. I have to be ready at all times," he told The Chronicle.
"I don't know how bad Rob's injury is, but I will prepare as if I am playing in the next game and if that happens I'll go into it with confidence. If I get a run in the team, I'll be just as confident in every single game as I was on Saturday.
"This win and performance does give me massive confidence."
Newcastle's first-choice goalkeeper Tim Krul is out of action until the New Year with an ankle injury.
