Pre test match nerves abound as England prepare to take on Australia in the third test at Perth despite recent performances. The pessimist in me awaits the wounded tiger to roar again whilst the disruption to our bowling attack is the dark lining to our silver cloud which raises the doubts. One injury enforced change is nothing compared to the form induced replacements that Australia have had to make, so why do I worry over the relative inexperience of the likely replacement for Stuart Broad, Chris Tremlett when Australia seriously consider selecting Michael Beer who has only played a handful of first class games. Perhaps fear of the unknown comes into it as we Tremlett is a good bowler but is unproven at this level and questions over his accuracy give cause for concern whereas I had not heard of Beer before this tour (neither had many Aussies either) but because of that you worry that he must be good to be called up so soon and recommended by Shane Warne. The feeling that we have used our run quotient up now and we're due a few failures doesn't help my nerves either but hopefully these are all unfounded.
