Alastair Cook says England are lucky to have James Anderson after watching the fast bowler become the country's top ODI wicket-taker.
England opened their Champions Trophy campaign with a comfortable 48-run victory over Australia at Edgbaston.
Anderson broke Darren Gough's record of ODI wickets as he moved on to 237 with three Aussie scalps at a cost of just 30 runs.
Cook said: "He's a great bowler, he just keeps getting better and better, we're lucky to have him.
"I think they were 30 for one off 10 overs and Jimmy and Stuart Broad were exceptional, not many freebies at all, and it's what you expect from experienced cricketers and they delivered."
England posted 269-6 in their innings, Ian Bell top-scoring with 91 and Ravi Bopara (46no), Jonathan Trott (43) and Cook (30) also making valuable contributions.
At 189-2 the hosts would have hoped for a total in excess of 300, and the Australians looked in the game at the halfway point.
Cook insists he felt 269 was a winning total. "From the position we got ourselves in we could have, and probably should have, got around 300 but credit to the way they bowled at the death. Little bit frustrating but I thought 270 was always going to be enough," he said.
"It was a good performance all round, I think it was a good toss to win. Clearly after 30 overs of our batting the pitch got slower and lower and we thought 270 was a good score."
Bell was man-of-the-match and he said: "The important thing was to win today, it doesn't matter who we were playing.
"It's the first game of the tournament and we wanted to get a good start; whether it's Australia or Sri Lanka wasn't that important today, it was about getting off to a good start and focusing on what we do well."
