The Brazilian, who was linked with a January move away from the Emirates, has confirmed he has struggled without first-team football this term.
"I'm trying to adjust to the situation, but I confess it's not been easy," stated Gilberto.
"I love the club and Arsene is a good man and a good manager - but there are only two months to go and I haven't played much.
"I will wait until the end of the season and then make my decision. If a good opportunity comes along then I don't see any other option."
