Reports suggest Galatasaray are interested in bringing the defender back to the Süper League.
The club's chief executive, Lutfi Aribogan, told Turkish newspaper Fanatik (via ESPN): "Andre Santos is one of the names on our list. We currently have no contact with his club and the player himself."
The transfer would be a bold move for Santos.
He enjoyed two successful years with Fenerbahce before joining Arsenal in 2011. Signing for his former club's rivals isn't going to win him many fans on either side.
Galatasaray's interest could kick Santos back into life at the Emirates.
The player has made just two substitute appearances in the Premier League this season.
He has averaged 1.5 tackles and 0.5 interceptions per match. The Brazilian has also made an average of one clearance across each outing.
Santos will find it difficult to displace Kieran Gibbs if he stays. The 23-year-old has capitalised on Santos' fitness problems and maintained his starting position with excellent form.
Gibbs has started all seven of Arsenal's Premier League games this campaign.
He has made an average of 3.7 tackles and 3.4 interceptions per match. The Englishman has also contributed 3.1 clearances per appearance.
Arsene Wenger's decision to continue playing Gibbs has been a fruitful one.
The defender has made the left-back position his own for the first time in his career. Alongside the much-improved Carl Jenkinson, Gibbs' displays have ushered in a fresher feel to Arsenal's play.
The manager couldn't ask for anything more amidst an injury-hit season for the club.
While the squad's younger talents continue to improve and work hard for the team, Santos has been creating headlines of his own.
His biggest impact of the season came in Hendon Magistrates' Court, where he landed a 12-month ban from driving (via BBC Sport).
A 145mph police chase is perhaps the last significant action Santos will see in England.
It seems the disappointing defender has two months to save his Arsenal career. Wenger's side has progressed since the start of the season and cannot afford to let off-field incidents tarnish the hunt for trophies.
If Santos put as much effort into aiding his colleagues as he does evading the police, he may be rewarded with a longer stay at the Emirates.
Should Arsenal let Andre Santos leave the club? Has he lived up to expectations since joining? Let me know in the comments section below.
