Toby Booth played down the fact Munster emerged from the Madejski Stadium shoot-out with a last-gasp losing bonus point and said that shouldn't detract from his side's performance.
With the clock counting down the seconds to full-time, Munster mounted one last attack and Ronan O'Gara managed to create a try for Sam Tuitupou that brought the Irish side back to within seven points.
That left the visitors with something to cling on to from a game in which they had only led for three minutes and at one stage were losing by 14 points.
"I thought we were good value for our victory and I'm absolutely delighted," said Booth, who guided his side to victory over the defending champions Leinster in Dublin in the first round of last season's competition.
"The bonus point is completely irrelevant for me. In a tough Pool you expect bonus points to be important, but if we win all your games they don't matter."
"We controlled the game from five minutes in to five minutes from the end. We are renowned for our attacking game, but just look at how we defended."
"It was a massive contest that took a massive amount of effort to be in a position of control in the game. You don't win a game in 40 minutes against a side like Munster who have won all they have done."
