Arsenal have confirmed midfielder Denilson has returned to former club Sao Paulo on loan for the 2011-12 campaign.
The 23-year-old, signed in August 2006, struggled to hold down a regular place in Arsene Wenger's side last season.
The Brazil midfielder is looking forward to getting back into action. He said: "I will be playing in Brazil next season as I felt that this is a good opportunity for me to play regular first-team football."
He added: "I move away with sadness because I have so many friends at Arsenal and everyone has always been so supportive towards me.
"I'm now focused on doing well in Brazil next season, but will always be looking out for the Arsenal results.
"It is a great club with many great players, a good team spirit and a top-class manager. I wish you well for next season."
