The Portugal Under 21 international has struggled with a troublesome groin injury for several months.
He told the club’s official website: “The injury is getting better bit by bit
“I’ve been doing ball work for five or six days now and I am running three times a week. I’m nearly pain-free and hope to be back as soon as possible.
“It’s been difficult. I’ve been injured for a long time but Arsenal have shown faith in me. They have got me in great shape and been brilliant.
“They monitor me with a daily programme and a trainer is there for me every day. I think that little by little I’m getting there and will soon be back on the pitch.
“I think that in two weeks I’ll be training with the team and if all goes well, I’ll speak with the manager and coaches here. Then I’ll be back as quickly as possible.”
