Indeed, Sharpe insists the controversial Melbourne Rebels star was as good as gold during his stint.
The former England fly-half was fined this week after being thrown out of a local nightclub - just days after kicking a last-gasp winner against ACT Brumbies.
"I spent quite a bit of time with Danny when he was here. He is a great lad, hard working on and off the field and looks after himself," insisted Sharpe when speaking with tribalfootball.com.
"We speak quite regularly. I am a rugby fan, obviously the Waratahs, but with Dan playing with the Rebels I have been taking an interest in how he and the team has been going."
Cipriani's spell with the Rapids caused a stir, with claims he was set to turn his back on the Rebels and devote himself to a soccer career.
Sharpe laughed: "He has a great left foot!
"He approached his training well and was always looking to improve his game."
