Keegan Makes First Signing - But He Hasn't Even Seen Him!
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 1.2million euros (£900,000) for Kadar - making him the most expensive defender in Hungarian football history.
Kadar: "My dream has come true, that I have signed to play for a club from the Premiership.
"My goal is, of course, to fight and grab a place in the first team as soon as possible.
"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."
