Lounis Lanseur (born 16 January 1989) is a former professional footballer who played as a defender. Born in France, he represented Algeria at international level.
Born in Saint-Étienne, France, Lanseur began his career at age 9 with his hometown club of AS Saint-Étienne.[1] He worked his way up the ranks of the club and became the captain of the reserve team in the 2009–10 season.[2] In the summer of 2010, when he was not offered a professional contract by the club, he left to join FC Libourne-Saint-Seurin.[1]
In January 2011, Lanseur was linked with a move to ES Sétif.[3] However, a month later, he ended up signing with another Algerian club, USM Blida.[4]
On 9 August 2009, Lanseur was called up by head coach Abdelhak Benchikha to the Algeria Under-23 national team for a week long training camp in Blida.[5] He was called up again later that month for another training camp.[6]
