The 30-year-old joined the Gunners from Newcastle United in the summer of 2014. In his first few months at the Emirates, injuries forced the France international to spend time on the sidelines.
Lack of options on the right-back position forced Wenger to field Hector Bellerin in that position. The Spaniard impressed in the full-back role and once Debuchy returned from injury, he struggled to break into the first team.
The former Newcastle defender was frustrated with the limited playing time and had discussed his situation with the Arsenal manager last summer.
