Career
He started his career in the youth system at Rennes and played three seasons in the reserve team before joining Tours in the summer of 2012. Boukaka progressed through the youth ranks at Rennes and made his debut for the reserve team on 10 April 2010, entering play as an injury-time substitute for Yoan Pivaty in the 1–2 defeat to Louisiana Vitréenne. After starting in the last four matches of the 2009-2010 season, Boukaka became more involved with the reserve side during the following campaign, making 26 appearances in total in the Championnat de France amateur, 19 of them as part of the starting line-up.
Rennes B were relegated to the Championnat de France amateur 2 for the 2011-2012 campaign after finishing bottom of their group at the end of the previous season, and the drop to a lower division saw Boukaka increase his scoring rate.
His next two goals both came in away defeats for Rennes, firstly at Saint-Malo in September and then against Vitré four months later. The goal proved to be his last for Rennes B, as he was not offered a new contract by the club and was subsequently released in the summer.
Following his release by Rennes, Boukaka had a trial at Ligue 2 side Angers but was not offered a deal. He eventually signed for fellow Ligue 2 outfit Tours ahead of the 2012-2013 campaign and made his debut for the side on 14 September 2012, coming on as a late substitute for Bryan Bergougnoux in the 1–1 draw away at Clermont Foot.
After starting the next three games, Boukaka returned to the bench and went on to make a further four substitute appearances during the first three months of the season.
