Rumen Trifonov (Bulgarian: Румен Трифонов; born 21 February 1985) is a Bulgarian former professional footballer who played as a defender.[1] He is currently working as a youth coach for CSKA Sofia.
Trifonov earned his first call-up to the Bulgaria national side in March 2011 for the Euro 2012 qualifier against Switzerland and the friendly match versus Cyprus, but did not feature in these games.[2]
On 22 February 2018, Trifonov joined Third League club Spartak Pleven.[3] In June 2018, he moved to Second League side Montana.[4]
Missing the most of the 2019–20 season due to an injury in the autumn 2019, 35-year old Trifonov decided to retire at the end of the year.[5]
In February 2020, he returned to PFC CSKA Sofia as a youth coach, where he became head coach of the players from 2004 and would also help the U17 team.[6] Beside that, he also signed for Kostinbrod in March 2020.[7]
