The 21-year-old joined Arsenal in 2011 but work permit issues have prevented him from playing for the Gunners, so he has spent spells on loan at several clubs, including Levante and his current side Almeria.
Next season could see Wellington finally make his Arsenal debut as he qualifies for a Spanish passport, but he is unsure of Arsene Wenger's plans.
He told AS: "I could go back to Arsenal next season if Wenger wants me to. But I am not going to worry about my future and my only desire right now is to help Almeria preserve their La Liga status. At this moment, I am focused on the present."
Almeria play Levante on Saturday, before hosting Barcelona the following weekend.
