The details of the loan are not yet known, but the former Zalaegerszegi man, who joined Newcastle in January, would follow the likes of Matty Pattison on the playing side and Lee Clark on the coaching side along the increasingly well-trodden route from St James' Park to Carrow Road.
Kadar, 18, made his first team debut for Zalaegerszegi at the age of 16. According to Wikipedia he was called into the full Hungary squad in May of this year.
