There are two very nervous teams in Brisbane right now. But it is when you drive to the ground on the first morning of the match that the stress of the Ashes really starts to show. As I remember it no one seemed too worried in the team meeting on the evening before the first Test in 2006. It was only when we were on the bus that it became clear how anxious the players were feeling. The atmosphere was so quiet. Nerves affect different people in different ways. Most players tend to go into their shells, though the odd one or two will become perky and try to crack jokes to lift the mood. What is obvious is that people are not being themselves.
