Leeds Carnegie completed a double over Crociati in the Amlin Challenge Cup as they won 44-6 on the road in Pool 4 on Sunday.
It was nip and tuck in the first half as the home side hit back after falling 12 points in arrears to reach half-time only 15-6 behind. But there were five second-half tries from the visitors to keep them in touch with pool leaders Stade Francais.
The unbeaten Frenchmen beat Bucharest Oaks 35-7 to move to 19 points after four rounds. Leeds are five points behind and have to travel to Paris in Round 5 in the New Year.
The Aviva Premiership Rugby side got off to the perfect start with a penalty try after only five minutes and then added another 20 minutes later from Michael Stephenson.
Ceiron Thomas converted one and then added a penalty before the break after Tommaso Iannone had clawed back six points with two penalties.
But it was one-way traffic after the break with the bonus point coming on the hour after further tries from Phil Nilsen and Welsh international Rhys Oakley. A last-quarter flourish saw Luther Burrell cross and then Henry Fa'afili crash over for a pair of tries.
