England will need "a 90mph bowler" and "big hundreds" if they want to win the next Ashes series in Australia, according to James Anderson.
Fast-bowler Anderson has been part of England's dismal tour, in which they relinquished hold of the urn having lost three out of the four Ashes Test matches so far.
And, with the final Test in Sydney getting underway on Thursday, the 35-year-old Anderson, who became England's all-time leading wicket-taker in 2017, believes that drastic overhauls in both batting and bowling will be needed when Joe Root's men next head Down Under for the 2020/21 series.
"I know my speed dropped off into my 58th and 59th overs," Anderson said.
"I was bowling the ball, looking up at the board to see what speed it was and then looking at Steve Smith hitting it. I tried a fair bit. The pitch was so unresponsive. It's quite demoralising when it gets to that point.
"There was a guy shouting at me: 'You can't bowl with a Kookaburra.' I said: 'You might have a point there.'
"But if you put Starc on that pitch - or someone who bowls above 90mph - they kind of take the pitch out of the equation. It would be great if we could get someone who could bowl 90mph-plus, just to have that sort of X-factor.
"I know it's a bit late [in my career], but if I can add another 5kph onto my bowling, that would be great."
Anderson feels that England's main issue throughout the series was their failure to put on big first-innings totals, while Australia had first-innings leads in the opening three Tests. It's something that the Burnley-native feels needs addressing.
Anderson continued: "We've got to score more runs. We need big hundreds. We've seen in all the Test matches, the team that has won or got on top has been the one with people scoring big scores, big hundreds.
"In this game in Melbourne it was us because of Alastair Cook, but it's one area we need to improve.
"Smith is a world-class player in the form of his life. It's going to take something special to get him out. On pitches like Melbourne, it is very difficult. In the first innings, it was a chop-on [that dismissed him]. You've got to hope for something like that sometimes.
"I'd feel disappointed for this group if we didn't get a win on this trip because we've worked so hard. We have played well at times in all four Tests. It would be nice if we can carry that on and have one last push at Sydney and try to get a win."
