Arsenal wing-back Andre Santos has completed his season-long loan move to Brazilian side Gremio.
Gremio unveiled the 29-year-old as their latest recruit on Monday afternoon after he passed a medical.
"I came to be a champion with the club," Santos told Gremio's official website.
Arsenal signed Santos from Fenerbahce for 6.8million in August 2011.
However, the Brazil international has fallen down the pecking order at Emirates Stadium behind England left-back Kieran Gibbs and, following the deadline day arrival of Spaniard Nacho Monreal, is now surplus to requirements.
A picture of Santos arriving in his homeland, where he last played for Corinthians in 2008/2009, greeted by cheering fans was posted on Twitter.
Meanwhile, Arsenal forward Lukas Podolski put a post on his official Twitter account which read: "@Andre_santos27 We will miss you man, I wish u all the very best #Gunner God bless you".
