Wellington signed for the north London side from Fluminese in January 2011 and is a former Brazil Under-17 international.
However, work permit problems have prevented the 22-year-old from playing for the Gunners’ first-team and has had spells on loan at various clubs, including Real Murcia last season.
But the striker was granted his work permit back in October and has now confirmed that he will be able to play for Arsene Wenger’s side from next season.
Wellington is quoted as saying by Metro: “It’s a dream for me to play there. Arsenal is a great club.
“Unfortunately this was not possible because of these administrative concerns, but I’m ready now. If all goes well, I’ll be out there next season.”
Arsenal are gearing up for Saturday afternoon’s Premier League clash with West Ham United at Emirates Stadium.
The Gunners, who are currently third in the Premier League table, head into that game on the back of their 2-1 FA Cup quarter-final win at Manchester United on Monday night.
