England were aggressive while batting first and scored 202 runs for the loss of 3 wickets in 25 overs.
However, in an attempt to continue the approach, Australia would then be aggressive in their own way of going about the chase and won the match by 49 runs via DLS method. Despite the loss, Brook said that the new approach will benefit England in the long run and thought they executed it perfectly.
"It's not just the present now, we're looking long-term," said Brook, who was named the ODI player of the summer.
"We're trying to build towards the bigger series and competitions. It's a new brand of cricket we're trying to play, and I think we've done that perfectly."
"Getting out of the power play, we didn't get the wickets we wanted, but outside of that, we've done really well."
Something I might think about: Brook on captaincy
Brook was happy with his own form as he scored a hundred and 2 fifties in the final 3 ODIs. The stand-in skipper said it was nice to finally get the tempo of ODI cricket. Brook also said that captaincy experience was good and it is something he will think about in the future.
However, Brook said he is going to sit back now and let Jos Buttler take over.
"It's nice to get on the board, score a few runs and contribute to some wins. I haven't played too much, but it's nice to finally get the tempo of ODI cricket."
"Captaincy has been good. It's something I might think about in the future, but I'll sit back and let Jos do it for now," said Brook.
England and Brook will now turn their focus to the upcoming Test series against Pakistan.
