The 19-year-old forward enjoyed an exceptional debut campaign at the club.
And Wright thinks the young Brazilian can learn plenty from 32-year-old Willian, who joined from Chelsea on a free transfer last week.
"He [Willian] creates chances and scores goals and that's what we need," Wright said on his official YouTube channel. "There's that Brazilian connection and getting a player like Willian has got to be good for our young players because he's a winner.
"The more winners we can get in there the better. David Luiz is a winner.
"I don't care what anyone says, I will always come out and back David Luiz whatever happens because I know his heart is in the right place and he wants to do the right thing for our club.
"I think he will transfer that into Willian and Willian will start feeling what we're about.
"That's only going to help Gabriel Martinelli, to have two experienced compatriots and Brazilian team-mates that he's being involved with. I look at it from a playing point of view and it's win-win for me."
