Mathieu Debuchy left Arsenal to join Saint Etienne on deadline day.

Mathieu Debuchy has sent Arsenal fans a goodbye message on social networking site Twitter following his free transfer to French side Saint Etienne on deadline day.

The 32-year-old fullback saw his contract terminated by Arsenal on Wednesday, allowing him to move back to his native France with Saint Etienne, who are currently sitting in 14th spot and two points above the Ligue 1 dropzone.

Debuchy never had the best of times at Arsenal, yet he holds the club in high regard and took to Twitter to wish his former teammates and supporters well for the remainder of the campaign.

The former Lille man joined Arsenal in 2014 after impressing at Premier League rivals Newcastle United.

Regarded as a competent fullback who can provide attacking options going forward, Debuchy was handed the number two shirt upon his arrival and tipped to go on and become a mainstay in the first-team.

Unfortunately for both club and player, Debuchy struggled for fitness and managed to make just a handful of appearances during his three-and-a-half year stay in North London.

His last outing for the club wasn’t a memorable one and arguably sealed his fate, as he struggled to make any sort of impact during Arsenal’s shock 4-2 FA Cup defeat to Championship side Nottingham Forest last month.

Debuchy wasn’t the only player to leave Arsenal on deadline day, as fellow Frenchman Olivier Giroud joined Chelsea while Krystian Bielik, Jeff Reine-Adelaide and Chuba Akpom departed on loan, freeing up some wages for the arrival of striker Pierre-Emerick Aubameyang for a reported club record £56 million fee (the BBC).
