The Age

Australia made a horrendous start to the Lord's Test match and as the byes, bad balls and misfields piled up, so the crowd began laughing at their incompetence. Mitchell Johnson's collapse was the main problem. It was painful to see a fine bowler try hard and achieve so little. He has fallen apart. His approach to the crease lacks conviction. He seems uncertain whether to bowl fast or rely on swing. Inevitably, the batsmen sense his hesitation and pounce upon it.

With Glenn McGrath retired and Brett Lee under-prepared or unavailable, Mitchell Johnson stepped up superbly. He was Hercules in India last October and November, carrying a struggling attack on his broad shoulders. That form continued in Australia and South Africa over the summer. Johnson was unquestionably the new spearhead. Now there is conjecture as to whether he will play the next Test, with the metronomic Stuart Clark waiting impatiently on the sidelines.

Mitchell Johnson might have claimed his 100th Test wicket, but his Ashes campaign hit crisis point with one of the most erratic new-ball spells in history. The major talking point was undoubtedly his terrible form. A dejected Johnson bowled with a low, slinging action, a scrambled seam and had poor body language as his confidence appeared shot. He certainly didn't look the man who led the attack so superbly in South Africa. He clearly hasn't adjusted to local conditions.
