A former Bulgarian top-flight goalkeeper has denied being involved in attempts to manipulate matches at last month's Under-19 European Championship.

Daniel Gyaurov, who played for Lokomotiv Sofia and Vidima-Rakovski, was arrested and held for 24 hours following a joint operation involving the interior ministry and the Bulgarian Football Union (BFU) on Friday.

Gyaurov, 20, who is a former member of the Bulgarian youth team, is alleged to have tried to convince some of his former Under-19 teammates to throw matches at the tournament.

"I'm completely innocent. I don't know who did this to me but it's disgusting," Gyaurov told reporters.

Bulgaria lost their three games and finished bottom of Group B without scoring a goal at the competition in Hungary.
