Career
Born in Domont, Val-d"Oise, Buval joined Bolton Wanderers at the age of 16 from AS Nancy, but he never broke through to the first team as a senior, being limited to reserve football and also suffering from recurring knee problems. In November 2006, he returned to his country and signed for Football Club Red Star Saint-Ouen in the Championnat National. In July 2007, Buval agreed to a two-year contract with Danish Superliga club Randers Football Club, joining after a trial period as a replacement for Djiby Fall who had left at the end of the previous season.
He struggled initially to become a first-team regular and, with Søren Berg and Marc Nygaard (both former Danish internationals) joining the team during the winter break, he received additional competition.
Eventually, as Berg moved to right midfielder, the Frenchman begun appearing more, and finished the campaign with seven goals in 27 games. Buval signed with Panthrakikos F.C. in Greece on 30 July 2009.
On 13 January of the following year, he moved to fellow Superleague side Panionios Football Club, scoring only three goals combined during the season and suffering relegation with the former. In the 2010 summer Buval changed clubs – and countries – again, joining Lechia Gdańsk from Poland on a one-year deal.
He was released on 3 July 2011.
On 16 September 2011, after a successful trial, Buval signed for two years with Communicative Disorders Feirense in Portugal. He was awarded the Primeira Liga"s SJPF Player of the Month award for the month of December, after scoring against Vitória de Setúbal (1–1 away draw) and U.D. Leiria (two goals, 2–1 home success), and finished the season as club top scorer but the team was eventually relegated just one year after promoting. On 23 July 2012, Buval joined Göztepe South.K. in Turkey on a three-year contract.
On 31 January of the following year, however, he changed teams and countries once again, signing for Denmark"s Vejle Boldklub Kolding until the end of the campaign.
In the following years, in quick succession, Buval represented Académica de Coimbra, F.C. Paços de Ferreira, South Carolina (U.S.) Olhanense and Flamurtari Vlorë, signing a two 1/2-year contract with the latter on 28 January 2015 for a reported €11,000 per month. He left on 17 October, claiming he was not being paid by the club
In February 2016, Buval joined Football Club Carl Zeiss Jena in the German Regionalliga Nordost. Buval chose to represent Martinique internationally.
