Vuckic: "My loan expired on 10th March and I got told on Sunday morning that I needed to come to London and that I was in the squad.
"I was surprised - but happy as well, and it was a very good experience.
"It was quite a disappointing night for the team because we were really fighting for that point and it's always disappointing when you concede a goal in the last minute, but we just have to stick together and look forward to the next game on Sunday, and try to win.
"I made my full international debut against Scotland.
"I played a couple of games, which was a good experience and good for my confidence.
"I got fitter as well, so the loan has helped me a lot.
"They were happy with me. I just trained as well as I could and when I got an opportunity, I tried to play well. I came on as a sub against Bristol City last weekend.
"I was very motivated and we got a goal, so I was very happy because I really want Cardiff to get promoted.
"When you're on loan, you have to switch on and just concentrate on that club.
"I know that Newcastle is my first club but having spent time with Cardiff, I will be happy for them if they go up. And I was really pleased that they got a win which means they're back in the play-off places.
"Hopefully they'll keep winning games and get into the play-offs.
"We'll see what happens. The gaffer will decide, Newcastle will decide - and I will be happy with either option. If they decide I should go back, I'd be very happy to."
