Agent hopeful that the 21-year-old can make his Gunners debut in the 2015-16 season.
Arsenal attacking midfielder Wellington Silva will join Almeria on a season-long loan.
Wellington, 21, signed for Arsenal four and a half years ago, but he has yet to play a competitive game for the Gunners due to work permit issues.
Since January 2010, Wellington has been sent out on loan to Levante, Alcoyano, Ponferradina and Murcia.
After completing his new loan spell at Almeria, Wellington will be a Spanish citizen, enabling him to make his Arsenal debut at the start of the 2015-16 season.
“A deal has been agreed between Arsenal and Almeria for Wellington Silva to go on loan for the season,” Alex Soares, Wellington’s agent, told Sky Sports.
“He had the choice to go to a number of teams in Spain, but Silva has decided to join Almeria.
“He will fly to Spain next week to complete the paperwork to join Almeria for next season.
“We are hopeful that, after this loan at Almeria, Silva will be able to return to play for Arsenal and they will monitor his progress in Spain next season.”
Wellington, who generally operates as a second striker or on the wing, represented Brazil’s Under-17 side 11 times between 2008 and 2009, netting five goals.
Wellington could become the seventh Brazilian to play for Arsenal in the Premier League, following in the footsteps of Andre Santos, Sylvinho, Gilberto Silva, Edu, Denilson and Julio Baptista.
