The north London outfit have agreed a £17 million deal with Corinthians for the versatile midfielder, with the move expected to be completed following the Selecao's involvement in the Confederations Cup.
Paulinho notched his second goal of the tournament four minutes from time in Wednesday's 2-1 semi-final win over Uruguay to send Brazil into Sunday's final, and Luiz is excited at the prospect of the 24-year-old plying his trade in England.

The win over Oscar Tabarez's men keeps up Brazil's 100 per cent record in the competition where they will now face either Spain or Italy on Sunday, and Luiz feels the squad are continuing to improve as they advance in the tournament.
"It's growing game-by-game but sometimes you cannot play the game you want with a lot of opportunities and a lot of possession," Luiz explained. "But that's why the Brazilian team is now more mature, because it can play open games or games like today, which was a very different game.
"I think Uruguay did a great job with two lines deep so you can't create a lot of opportunities to score but the team has matured well.
"It's a dream come true [to reach the final]. I think it is a special moment for us, but we want to win.
"I am so happy because I can play a final with Brazil in the Maracana. Whether we play against Spain or Italy, it will be a difficult game for us."
