Prior to his arrival in Portugal to sign with
Vitória de Guimarães for the
2006–07 season (with the club in the
second division, finally winning promotion), Paris-born Desmarets played the vast majority of his career in modest French clubs, never appearing in higher than the
third level. He quickly became an undisputed starter, contributing with four goals in all 30
Primeira Liga games as the
Minho team overachieved for
a final third place in his second year, ahead of
Benfica. In June 2010, after only missing four league matches combined in two top level campaigns, adding four goals, 30-year-old Desmarets signed as a
free agent for one year with
Deportivo de La Coruña in Spain, with an option for another one. He only appeared in 12
La Liga games during
the season – 693 minutes of action – which finished in relegation. After a failed trial with
Montreal Impact, Desmarets joined
Kerkyra in Greece for 2011–12, appearing in no official matches. In early July 2012, he signed for
Belenenses on a
free transfer. ==International career==
