A recent injury for Ba has scuppered a move to West Ham
Payet went on strike in order to push through the move, despite the player having signed a £125,000-a-week contract at the London Stadium just a year ago.
He was named Player of the Season at West Ham last term but his performances this campaign dipped.
But Sullivan insists he doesn't regret first signing the France international.
"What Dimi said to me is that his family hadn't settled," Sullivan told talkSPORT.
"He wanted to go back to France. It was very strange what he said after moving.
"I don't regret bringing him to the club. We finished seventh and a lot of that was down to him. He was Player of the Season last year.
"It's ended a bit acrimoniously. Life goes on.
"In the real world you've got to see it all in perspective. It's a damage limitation deal."
