The NBA champion, who won a title with the Warriors in 2015, shifted to Dallas to make way for Golden State recruit Kevin Durant.

He missed the last two games of last season's finals series loss to Cleveland which drew criticism from “sources” at the club who bagged Bogut in the media for being injury prone.

"I don't buy into the sources thing. I don't buy into all that s**t because this league is so two-faced and everybody is so fake," he told USA Today.

"The same people who made those comments will see me tomorrow and shake my hand and ask me how my family is. This league is full of people who are full of s**t and shallow.

"It's very hard to meet a genuine person who you can call your friend in this league."

Bogut said he had no ill feelings toward his former club ahead of his return.

"There's no doubt it's disappointing to leave one of the best teams record-wise those last two years," he said.

"It was bitter in a way. I wasn't mad at anybody about it. I understood it completely. I'm not stupid."
