Gilberto is confident of establishing himself at Tottenham next season.
The Brazilian left-back told the club's official website: "I feel like I've learnt a lot about the Premier League and the team. I've also enjoyed working with the coaching staff and the players.
"Next season I'm hoping to improve on a personal level and speak better English.
"My family have adapted to life in England, so the last few months have been important for me."
