The Brazilian international finalised his switch to White Hart Lane earlier today from Corinthians in a deal thought to be worth around £17m.
Having signed on the dotted line, the 24-year-old has now turned his attention to helping his new teammates to win trophies.
"First, I want to thank Tottenham for believing in me," he told the club's official website. "I am very happy and excited to have joined Spurs.
"It's a huge pleasure for my career to be at a club as big as Tottenham. I know it will be a huge challenge but I think I can help all my colleagues to succeed and give a lot of happiness to the supporters."
Paulinho has earned 17 caps for the Brazilian national team.
