The loanee made 10 appearances for Orient before the curtailment of the season and very quickly made an impression in E10. Ouss managed one goal in that flurry of games, nodding home Josh Wright’s free-kick against Stevenage United.
Cissè came through the youth system at French giants PSG but kick started his career with Amiens in the French third division. A professional debut came in August of 2011 as his team reached Ligue 2.
After three seasons with ‘Les Licornes,’ Ouss made the switch to Dijon FCO. The Mali international went on to make 93 appearances for the club and scored five goals.
A move to Spanish side Rayo Vallecano in 2015 was next for the midfielder, but opportunities were hard to come by and a loan switch to Belgian outfit Waasland-Beveren soon followed.
The following summer, Cissè agreed to parted ways with Vallecano and returned to France and Ligue 2 to play regularly for Tours.
MK Dons swooped for the then 26-year-old Cissè in the summer of 2017. Having been relegated in his first season at the club, Ouss was a part of the side that fought for promotion back to League One the following campaign.
Leaving the Dons on a high, Cissè joined Gillingham ahead of last season and made five appearances, before moving to the O’s on loan at the beginning of 2020.
