Munster head coach Johann van Graan hailed JJ Hanrahan after the out-half kicked a last-second winning drop-goal in Treviso.
The winless Italians led 16-15 as the clock ticked past 80 minutes.
However, Munster held possession under pressure, and worked their way into a position to give JJ Hanrahan a chance to steal the game back.
The out-half delivered for an 18-16 win that extended Munster's lead at the top of Conference B to 15 points over second-placed Connacht.
"We played against a very good side tonight," Van Graan told eir Sport. "We started the game really well, got some momentum and scored two good tries.
"But it was a big breakdown battle. Benetton worked very hard. We stuck to it right until the very end and for Munster, it is never over until the final whistle goes.
"What happened at the end (when Hanrahan scored his last-gasp drop-goal) is in our armoury.
"When you get to a three-point game, at the final play of the game, you need a good maul as well as good composure. We had that.
"So for JJ to get that score was just marvellous."
