Aironi lost their winger Guilio Toniolatti to the sin bin just two minutes after the start of the second half for tackling Warwick in the air and while he was off Munster scored their opening try when Donnacha Ryan picked off a wayward long throw to the tail of the line-out to cross unopposed.

Warwick converted and he again added the points after Munster were awarded a penalty try in the 56th minute. 

The victory leaves Munster eleven points clear at the top of the table.
