SIX-TIME league champions Rayon Sport Football Club have sacked assistant coach Ali Bizimungu accusing him of not being committed to the job and "not having a good relationship” with head coach Didier Gomes da Rosa.The club chairman Abdallah Murenzi, who is also the Mayor of Nyanza District confirmed to Times Sports yesterday that Bizimungu has been relieved of his duties with immediate effect.However, the club has not named a new assistant coach, but according to the official, Technical Director Thierry Hitimana will assume the role temporarily until a permanent replacement is found."I can confirm that Bizimungu is no longer working for Rayon Sport. He is not with us anymore. We have asked him to step down after we realised he was not committed to his job. The club will look for another assistant coach in the coming days,” Muranzi confirmed.He added, "We asked him to go as he has not only been committed to the job but his working relation ship with the head coach has been deteriorating by each passing day.”Bizimungu follows his assistant coach Abdul Mbarushimana who resigned from his duties, citing poor working relationship with his bosses last year. But when contacted, Bizimungu feigned total ignorance about being sacked, insisting that the club has not contacted him regarding the development."To say that I am not committed to my work is wrong because I have been dedicated to my job.  Maybe it is something else, but I am waiting for the (sacking) letter,” the former Kiyovu and Mukura coach told Times Sport.Meanwhile, the club has released three players; Dhorasso Karangwa, Sacha Dusange and Francois Flamini Usanase as they are not in the French coach’s plans.The Nyanza-based club is in 7th position in the Primus National Football League table with 16 point, 5 points behind leaders AS Kigali.
