He has won seven England caps but has not played international rugby for two and a half years, having been out of favour for most of Martin Johnson's time in charge.
Sale first-team coach Tony Hanks, who worked with Cipriani during his time at Wasps, told
BBC Radio Manchester:
"He's a quality player. I've known Dan since he was at school, he was there in my first stint at Wasps and he was obviously a good player from when he was young.
"I think Super Rugby has been good for him and I'm looking forward to seeing how he's going to go in the second year.
"He's still young and fly-halfs in my mind don't mature until their late 20s. I think that's why someone like Dan Carter has been such an exception, because it does take time to learn the game.
"Regardless of where he goes it will be great to see him back plying his trade back up in the UK."
