The Slovenian international's campaign was halted early last term due to a knee problem sustained in training after his loan stint with Cardiff City came to an end.
"It helps to go out on loan as a young player," he told the Evening Chronicle.
"Not only do you gain the experience but you also get fitter too. It helps your confidence as well.
"I would be happy either way next season whether I go back or stay at Newcastle.
"The gaffer will decide what is best."
