Former England batsman Geoffrey Boycott has no doubts that Australia can clinch the current Ashes series 5-0 after winning back the urn on Tuesday.
Australia outclassed England during the first and second Tests before claiming victory by 150 runs in the third meeting in Perth to end a run of three-straight defeats in The Ashes.
"This is a possible 5-0 now. Sometimes you can turn it around a bit but I see too many problems in the England side," Boycott told BBC Sport. "England can't make enough runs to win matches. Look at Prior's dismissal this morning - it was a wide ball which didn't move and he showed no footwork and edged behind.
"Australia have planned well for players like Cook and Pietersen with their bowling and field placings. It's the same management team which weren't winning but they have managed to pick the players up. This is where the England coaches earn their money, when things are not going well.
"On paper, there is nothing to choose between the teams but one has got it significantly right in performance and planning. The other has cocked it up big time."
The fourth Test gets underway on Boxing Day in Melbourne.
