English squad thoughts:
Cook
Denly
Vaughan
KP
Collingwood
Bell
Ambrose
Anderson
Sidebottom
Tremlett/Harmison
Panesar
Denley ahead of Carberry where I am concerned. Have liked the look of Denley whenever I have watched him and given that it is 18 months still to go, there is a fair chance that Denley might play if he piles the runs. It is a long shot neverthless.
Bowling wise, some one mentioned that he fears that Hoggard might not be able to last that well for 18 months from now and that is fair enough I think. He would be 32 and a half and despite his ability to swing the ball, he is more likely not to make the XI than to make it imo. Will he be able to put away the injury concerns and be match fit? It makes me put a question mark over him.
I disagree regarding Anderson and liked what I saw during the India - England test series. If he can go from strength to strength, I can see him as a crucial member of the squad.
The dark horse for the XI would be Simon Jones. If he can make a solid come back, he would have a bit of a chance of making the XI.
About Flintoff, I would say that there is more chance that he will not play than he will play at this point like wpdavid said earlier in the thread.
I am not sure who would keep in the Ashes but the back to back series v New Zealand should make things clearer regarding this aspect.
Australian squad thoughts:
Hayden
Jaques
Ponting
Hussey
Clarke
Watson
Haddin
Lee
Johnson
Clark
MacGill/McGain/any other spinner
Watson would be a huge asset for the squad given his clean hitting, the smaller grounds in England and the balance he adds to the squad.
England are not great players of spin traditionally and though they have become better at it, they are not the best still and I would imagine that Australia would like to go in with a specialist spinner. I fancy MacGill here. He has 39 wickets @ 24 against them, the best among major test nations in terms of wickets and average. He has shown an almost desperate hunger to play more and even though he has declined a tad in recent times, this could be his last hurrah. A spinner also plays the role of the stock bowler when need be and I certainly expect Australia to go in with one spinner... if not MacGIll, then some one else.
Johnson is developing well and improving in aspects of his cricket. He can be a real threat in the series and I will be very surprised if he doesn't play.
The dark horse for the XI would be Shaun Tait. Like Jones for England, If he can make a good come back, he would have a bit of a chance of making the XI.
Of course, these are only what I think might be the squads. Don't kill me if Denly proves a complete failure between now and then and Hoggard and Flintoff have superb Ashes series as there is every chance that might happen as well. 18 months is a long way away and a lot can happen between now and then. It should be superb series to watch whatever happens.
