Murphy has not played for England at any level since the 2017 European Under-21 Championship.
He reportedly turned down a chance to change his international allegiance to Nigeria, where his biological father is from, earlier this year.
And he is hoping for a first senior call-up this summer by Thomas Tuchel. He was given encourgament by Magpies team-mate Dan Burn, at the age of 32, making his England debut under the German during the last international break.
“Dan has not only been a really good friend but he’s been a great inspiration for myself and a lot of people in the dressing room,” said Murphy.
“To see him getting the accolades and for people to really appreciate him as a player at 32, that is added incentive.
“Dreams of playing international football can still be there. Credit to the new manager for putting faith in Dan at such an age. Hopefully people at 30 aren’t being overlooked. 30 is the new 25!
“It’s something I can see. But I know taking care of my club form is going to give me the best opportunity to represent my country.”
