Fluminense striker Wellington Silva is set to take part in Arsenal preseason training.
Flu president Alcides Antunes has confirmed the 17 year-old will be joining the Gunners officially next season.
"It's in the contract. We cannot do anything. I have not received the request yet, but there's no problem," he said.
Wellington will be eligible to play competitively for Arsenal when he turns 18 in January.
