Braveheart81 - They have announced the same squad and most press reports suggest Finn will be playing because it is his home ground. He has had plenty of success there but Anderson and Swann both also average around 28 at Lords so any of them could threaten us. Spin shouldn't factor until the second innings and I'm hoping we will see a lot more of Agar and Swann.
As for our charge, I think we really need Harris. He hits the deck hard and bowls a consistant line and length and doesn't tend to spray the ball as much as Starc. His role is similar to Siddle in that he is a genuine wicket-taker and match winner who can bowl for extended periods. This may work against him as we tend to want a left-arm express bowler who can move the ball. At Lords I'd prefer Harris who can keep the ball in the same spot and shut down one end, similar to Watson however a bigger threat of taking wickets. The ground is different to most in that the bowlers face a slope when running in and there is very little room for error with generally quick outfields.
I wouldn't be too worried if he isn't picked though, Starc has the ability to grab early wickets and is no mug with the bat.
EDIT: Just as I posted this Aus team is announced, Harris playing instead of Starc. Khawaja in too.
