On 15 July 2013, Radványi signed with Békéscsaba in the second division.[3] Half the season later, he was released alongside with Dániel Kiprich and László Mészáros.[4]
As a free agent, Radványi moved to Rákospalota in the Nemzeti Bajnokság III on 24 February 2014.[5] On 22 March 2014, he scored his first and winning goal for the club in a 1–0 win against Hajdúböszörmény who had the extra player advantage.[6] On 26 April 2014, Radványi was banned for four matches after he made a grossly offensive remark about the referee after a red card in a 2–2 draw against Veresegyház.[7]
Player Agent
In an interview, Radványi said that he choosed to be an agent for players after realising that his skills were not sufficient for professional football, which requires dynamism and speed. He is active in Hungary.[8]
