Radza joined OB's academy in 2009 from cooperation club FC Assens, after having started playing football for hometown club Ebberup IF.[2][3][4] In March 2012 Radza extended his contract with OB.[5] The first year of the contract was a part-time contract because he was to complete his education, after which he joined as a full-time professional in the summer of 2013 as the third goalkeeper. In June 2014, he extended his contract by another two years, keeping him at OB until 2016.[6]
On 28 January 2016, OB announced that Radza's contract had been terminated by mutual consent, as he sought a club that could provide him with regular and dependable playing time on the first team.[9]
Later career
Just three hours after Radza was released by OB, he joined the Danish 2nd Division club Næsby.[10] Six months later, on 26 July 2016, he moved to Faroese club TB.[11]
He remained at TB for five months before again returning to Denmark, signing a one-and-a-half-year contract with Danish 2nd Division club Middelfart in December 2016.[12] He evolved into a starter for the team, and on 15 December 2017, he extended his contract with the club until December 2019.[13] On 25 June 2019, he signed another contract extension, this time until December 2020.[14]
