Eventually, Newcastle stalwart Tim Krul arrived on loan on deadline day, but Oldfield believes Ryan will embrace the challenge that the Dutchman will bring.
"Mat Ryan will feel a little bit of pressure with Tim Krul arriving," Oldfield exclusively told Tribalfootball.
"However some keepers thrive off pressure and I can't see Matt Ryan being any different.
"Sometimes it's what is needed to kick into the next gear. What I have been told about Matt Ryan from his old keeper coach John Crawley is that he is a very hard worker."
"I have had to compete with keepers before for number 1 spot and it's about being patient and continuous hard work. Everyone gets a chance sometime in there career it's about being ready."
