Steve Williams, the well-known caddie who spent much of his career working for Tiger Woods, says he and his old boss still have unfinished business.

The Woods-Williams pairing ended in 2011 after more than a decade, and there have been angry words between the two since then.

Though the tension seemed to ease of late, Williams is once again talking about Woods in a two-part interview with Australia's Fox Sports. 

"There's been a lot of ... this, that and the other ... but the hatchet hasn't been buried," the caddie said. "It's just personal things and a difference of opinions on how things went down ... and I need to sort that out with him."

Referring to Woods' infidelity scandal in 2009, Williams continued: “So many people feel I must have known something, but I didn’t know. If I’d known something, I would have said [so]. I don’t sugar coat anything.”

Williams now caddies for Adam Scott.
