Daniel Illyes, who worked with the 16-year-old at the Eger goalkeeping academy, has hailed the youngster's potential and willingness to follow Hungarian goalkeepers Adam Bogdan and Martin Fulop to English football.
"He's an enormous talent, there's no doubt about that," Illyes told Nemzetti Sport. "Erik signed with us at 13 and we saw he had a big future.
"A year later Budapest Honved signed him and we can now say that Bolton have signed him for two years on a fellowship contract. It is evident that besides his talent, Adam Bogdan took him to Bolton."
