Bouhna started his career at the third-tier
Diegem Sport before he was spotted by
Anderlecht scouts during a friendly between the two clubs and arranged a transfer in the summer of 2012. He never broke, however, into the
Anderlecht first team, playing on loan at second-tier
SV Roeselare and in
Anderlecht's reserves. After a period as a free agent in late 2014, he signed with
Serie B side
Latina Calcio. Not finding much playing time, he left the club the following summer, signing for
NK Istra 1961 in
Croatia in September 2015. There, he made his first-team debut in the
Prva HNL in the 1-0 away loss against
NK Rijeka on 13 September 2015. On 28 December 2017, Bouhna signed a one-and-a-half-year contract with Bulgarian club
Lokomotiv Plovdiv. ==Honours==
