The Ashes 2013: Alastair Cook vows to turn up the heat on Australia Cook tasted a 5-0 defeat as an England player in Australia six years ago, seeing at close quarters how that great Australian side continued to raise their game after each victory. "Winning is a habit and these two Tests make it four Test match wins this summer," said Cook. It is a good place to be in. But we will not be taking anything for granted or taking our foot off the gas or looking beyond the first hour at Old Trafford. That is not how Andy Flower works and not how this England side works. We know how hard it is going to be in the next few games. The crowd at Lord's chortled when Clarke said during the post-match ceremony his team were still capable of winning the series and he admitted he did not blame them for their amusement such was the abysmal performance by his side at Lord's. "I am still confident we can win this series, I heard a lot of the crowd laugh when I said that and rightly so given the position I sit in now," said Clarke. But I think we have seen all of our top order make a fifty so far. We need someone to go on and make a big hundred like England have done. Our batting in the first innings was unacceptable. The wicket was very good for batting, we had a great opportunity and we let ourselves down. We have plenty of experience in our top seven and we have seen already in this series guys can score runs against this attack. Our shot selection was poor and we did not have the discipline England had. They were willing to graft through the tough times and we certainly weren't in that first innings. We are letting ourselves and our supporters down at the moment by the way we batted in first innings. The bowlers are fighting as hard as they can but we are letting them down by making them bowl every single day because they are not putting enough runs on the board. The last Australian captain to lose six Tests in a row was Kim Hughes in 1984 and he resigned in tears. Clarke said "presume nothing" when it was put to him he was unlikely to follow suit but did accept responsibility for his own performance in the match. "I'm as responsible if not more accountable for my poor performance in the first innings," said Clarke. The way I got out, I felt I was hitting the ball well, my shot selection was extremely poor. I expect better of myself and this team needs me to make sure when I get a start like that I go on and make a big score. Clarke will play at Hove this week in a three-day match starting on Friday and said he did not expect the selectors to choose from outside the Ashes squad, seemingly squashing chance of a recall for Simon Katich, who is scoring prolifically for Lancashire. Kevin Pietersen will undergo treatment this week on a calf strain which has left him a major doubt for the third Test at Old Trafford. It is a concern. He has a slight strain of his calf," said Cook. We have great medical team who will work non-stop to get him ready. He is a world-class player who would leave a big hole but if he is not available it gives someone else a chance to step up and there are some very good players not playing in this squad.
