The Cork-born centre back was happy to have made his competitive debut against Germany and insisted that the caretaker boss deserves plaudits for his professionalism
King has taken over the reins in a caretaker role while the Football Association of Ireland continues its search for a permanent successor to Giovanni Trapattoni and the 32-year-old says that the temporary boss deserves "a lot of credit" for how he has handled the entire situation.
"You have got to give Noel King a lot of credit in the week that we had," Delaney told RTE. "He started working on the game plan [against Germany] on Tuesday and I think he has been superb, and I genuinely mean that.
"The levels of professionalism that he had in everything that he has done in and the levels of communication have been absolutely brilliant with the players, in terms of on the training pitch and putting a game plan in place.
"He boiled down our job for us and everyone had a job to do, and when you have that, you know what you are doing and you look relatively organised. And we played some decent football, at times."
With regular centre backs John O'Shea and Richard Dunne serving suspensions, King handed the Crystal Palace defender his first competitive start in the 3-0 defeat against Germany in Cologne on Friday. Despite acquitting himself well, however, Delaney admitted that he would have "no problem" losing his place to the pair.
"I'm fully aware of where I am in the pecking order and when [O'Shea] and [Dunne] come back in they will fully expect to start and I've got no problem with that," he said.
"I'm just happy that I got my competitive debut tonight. It's just up to me to continue my club form and if I get a chance again through injury or suspension, I'll be ready to get a night like tonight because it was really special."
Republic of Ireland host Kazakhstan at the Aviva Stadium on Tuesday October 15. Kick off 19:45 BST.
