Munster head coach Anthony Foley believes his side did the best they could in tricky conditions for last weekend's bonus-point win over Treviso.
The two-time winners got off to the perfect start at home in the Champions Cup.
Foley praised the work of his half-backs Conor Murray and Ian Keatley as Munster ran out 32-7 winners.
"It is the best we played in those conditions," Foley told the EPC Rugby website.
"The way we controlled the first-half possession, we kept the play where we wanted and it was seldom that they got into our 22.
"I thought it was well marshalled by Conor Murray and Ian Keatley and the pack got through a hefty workload in terms of keeping the ball and moving it up the pitch through the maul and also by coming round the corner and running hard off nine.
"It was easier to handle the ball in the first half."
Next up for the Irish province is a visit on Sunday to Paris to take on Stade Français – a high-profile fixture in any week but especially so after the tragic events in the French capital.
"We know what's going to face us when we play the French champions Stade Français in Paris," Foley added.
"It'll be an emotional occasion, but it's about playing a game of rugby."
