The Brazilian made what was only his fourth Premier League start of the campaign at Newcastle on Wednesday night.
Gilberto, 31, has been linked with a move away from Emirates Stadium during the transfer window, but is determined to make the most of whatever chances come his way.
"It is nice to get a chance to play a full game but of course I am doing the best I can to get back in the team," Gilberto told the club's official website.
"I will see what happens but of course I want to play in the first XI and I will do my best to achieve that."
The 2002 World Cup winner added: "A big squad is important. At the moment we have a few injuries, but we have other players who can do a great job.
"The manager needs to change the team in some positions but we keep the same spirit and the same way of playing."
