Michael Clarke looks inward despite Ashes flop Michael Clarke on the his way after being bowled by Stuart Broad for 21 in Australia's forlorn chase Source: Getty Images Destroyer Stuart Broad celebrates taking the final Australian wicket to fall, that of Peter Siddle Source: Getty Images MICHAEL Clarke is facing the prospect of becoming the first Australian captain to lose an Ashes series in England 4-0. But despite the predicament the skipper backed away from calls for changes, saying he believes the best cricketers Australia possesses already are in the Test side. That was hardly in evidence at Durham overnight when Australia, at one stage 1-147 chasing 299 for a victory that would have kept the Ashes series alive, meekly capitulated to lose its last nine wickets for just 77 runs. In the end it tumbled to a 74-run loss to an England side it had dominated for the best part of three and a half days. The clamour already has started for there to be massive changes for next week's final Ashes Test at The Oval with a view to preparing the side for the next phase of the Ashes cycle in Australia next summer. Clarke, however, cautioned against making change for the sake of change. "I think we are picking the best players - everyone says rebuild, rebuild, rebuild but you need guys in first-class cricket making runs to take someone's slot," Clarke said. We have to continue to show faith in these guys. It takes time playing against good opposition. We just played South Africa in Australia, we are playing England here then England in Australia, then we go to South Africa. We are playing the best oppositions in the world. You have to select 11 players to take the field. You can't go out there with two players. You pick an Ashes squad which the selectors thought these were the best players for these conditions. I think the selectors are doing a fine job. It is not easy. Guys are not scoring as many runs as we would like in first-class cricket so it's very difficult for them. When you pick the squad you have to keep the faith and try and get the best out of them. And it would be nice if the captain led by example and scored a few more runs as well. As the wickets fell in clumps, it was difficult not to reflect that this was an Australian side that has not won in eight Tests up against an England team that hasn't lost in 11, but Clarke is adamant the side has not forgotten how to win. "Chasing 300 the last innings of a Test match is always going to be difficult, there is no doubt about that," he said. I don't think today was about forgetting how to win, I just think a good bowler got his back up and got momentum around with it and we couldn't stop him. England captain Alastair Cook came up with a masterly piece of understatement to described Stuart Broad's match-winning spell of 6-20 off just 45 deliveries. "It was a fine spell of bowling," Cook said. That's probably not the right adjective either. As a captain and knowing how important how that (last) session was...if we lost that session we would have been struggling. Broady knew that and the lads knew that. He really charged in. When everything clicks and bowling in the high 80mph with the control Broady has it's incredibly hard to bat. I said that against New Zealand when he got that seven-for at Lord's. It was similar to that. Here was more important in terms of the situation of the game and in the Ashes. Words can't justify how good a spell of bowling that was. Cook admitted he was more than a little anxious when Australia reached 109 without having lost any wickets but he never lost faith that in the end the victory target of 299 would prove too difficult for Australia. If you put two wickets on the score it changes things very quickly and we did keep saying that. At one stage you are thinking: Is it ever going to happen? Broad acknowledged that, for all of England's comfortable winning margin at the end, the game swung in the balance throughout the final day. In this game pretty much for each hour it could've gone either way. Certainly at 40-3 in our second innings we were staring down the barrel a bit. The emotion of it, the turning up at the ground each day not knowing what's going to happen, I think that's why the crowds are so captivated by it all. Every day is a journey and you have to put it to bed and start again. It's amazing to play in and amazing to watch as well.
