Eddie Jones emphatically rejected the notion England got lucky in its 30-6 win over Australia at Twickenham, after a number of marginal calls went in favour of the home side.
Tries in the final eight minutes from Jonathan Joseph, Jonny May and Danny Care enabled England to triumph by a wide margin on Sunday (AEDT), but all that followed a second no-try decision of the contest for the Wallabies.
There was plenty of controversy prior to the one-sided finale as Australia had two tries disallowed by the television match official (TMO) either side of Michael Hooper and Kurtley Beale being sent to the sin-bin.
The Wallabies also felt hard done by when Elliot Daly's 54th-minute score was allowed to stand, after multiple replays had been viewed in a bid to determine whether the ball had gone out of play.
Yet when Jones was asked in his post-match news conference if he felt his side "got a bit lucky", England's coach offered a spiky response.
"Why do we have a referee? Why do we have TMOs? I don't understand the question. How were we lucky?" he said.
"They do 10 replays of video and they make a decision. This is the best referee in the world for today [Ben O'Keeffe]. We had the best guys in the TMO [box] and you're saying we're lucky because the decisions went our way."
As his interrogator attempted to explain the reason for his question, Jones cut in by sarcastically saying: "I'm sorry we're lucky. I'm sorry, mate."
Jones's mood was brighter as he joked about his conduct during the match. The Australian had issued an apology after he was caught on camera swearing during last week's win over Argentina, but he was able to remain calm on this occasion as his opposite number, Michael Cheika, cut a furious figure.
"I didn't throw a pen today, I didn't swear. I thought I'd even it up with the other box," Jones said with a grin.
"I think my mother will be pleased. I don't expect a phone call at five o'clock in the morning tomorrow."
England has now won all five of its Tests against Australia under Jones, who added: "The only time I've ever seen 5-0 before was the 70-71 cricket. Australia got absolutely demolished, Bill Lawry got dropped as captain and Ian Chappell took over, which was the resurgence of Australian cricket.
"It's nice to win 5-0, but we're only as good as [the last] game and we know we need to keep improving."
