Kevin Keegan has completed his first capture as Newcastle manager in the shape of Hungarian defender Tamas Kadar.
The 17-year-old, who impressed The Magpies during a recent trial, has signed a four-and-half year contract at St James' Park.
Newcastle are reported to have paid Zalaegerszegi 1.2 million euros (£900,000) for Kadar - making him the most expensive defender in Hungarian football history.
"My dream has come true, that I have signed to play for a club from the Premiership," Kadar told Zalaegerszegi's official website.
"My goal is, of course, to fight and grab a place in the first team as soon as possible."
Kadar revealed that he is shocked by the progress he has made in recent years, having only taken up the game a few years ago.
"When I was 14 I wasn't a contracted footballer, I played only for fun and I wanted to become a handballer as I'm from Veszprem [the town has a well-known European class handball team]."
"I'm happy to get this contract but I don't want to be satisfied only with this. I'm studying English very hard and I want to become a good and successful player," added Kadar - who already has an Under-21 cap to his name.
Kadar is the third teenager to join Newcastle's ranks this month after the signings of Le Havre striker Wesley Ngo Baheng and Swindon defender Ben Tozer.
