Wenger signed the Brazilian as a last-minute recruit alongside Per Mertesacker and Yossi Benayoun.
Santos had one mission in solving Arsenal’s problems in the left-back position.
But the €7m signing was clearly not suited to Premier League football, with his lack of pace and poor positioning proving to be a real hindrance for Arsenal. So fans weren’t exactly overjoyed to see him.
The 36-year-old provoked the supporters even further by exchanging shirts with former Gunners star Robin van Persie midway into a 2-1 defeat against Manchester United.
Santos went on to play in Brazil, India, Switzerland and Turkey after leaving Arsenal in 2013.
He’s currently a free agent following his exit from Brazilian second division side Figueirense FC last January.
Andre Santos: "I couldn't win the title but I was very happy at Arsenal. Living well, training, but at Arsenal I saw no ambition to win. When I'm in a club, I want to lift the title, but I saw that #Arsenal didn't have that ambition" pic.twitter.com/0kOsyBoveq
