The 17-year-old defender has reportedly been the subject of a bid from Sunderland, while reports suggested QPR were set to send a scout to Saturday's game against Kilmarnock.
Turkish forward Ciftci - who netted the only goal as United claimed a 1-0 win in the Scottish Premiership clash - was a teenager himself when he moved to Portsmouth after a spell in Holland.
He said: "If he goes to another club, the important thing is the people around him, how they get on with him.
"He's really young but, at the end of the day, you just play football. If he enjoys that, it won't be a big problem.
"I was 15 but with me it was different because I didn't speak English at all when I came here.
"So, for him, it's easier. I don't think it would be a big problem for him.
"The important thing is that he plays day in and day out.
"If he gets that chance, and that opportunity to play down south in the Premiership, that's really good for him. He will improve but it depends on whether he is going to play or not."
Another United youngster who has impressed Ciftci is Ryan Gauld, who shone again against Kilmarnock.
He said: "Ryan did really well and I think he is getting better every day.
"He's still young and in this game he was one of the best on the pitch. He is one of the better young players I've played with.
"He's still very young but his composure and confidence on the ball impresses me and that's without mentioning his undoubted technical ability.
"The most important thing is if you're so young that you're confident and he's got it."
Ciftci netted the only goal of the game early in the second half to claim all three points at Tannadice.
He said: "It was a good ball from David Goodwillie and I took my chance.
"I could have scored more goals before that. We had a few easy chances but sometimes the harder ones go in.
"It doesn't matter. As long as you win, that's the important thing."
Kilmarnock are still without a win this season and slipped to 11th in the table following the defeat.
Boss Allan Johnston said: "It's concerning when you are losing games.
"We shouldn't be where we are just now. We should be higher up the table. But we are down at the foot of the table and it isn't good enough.
"We've got to work even harder and we've got to improve - the players and myself."
