Can't see there being many surprises in England's squad.
I'd take Foakes (or A Davies) as reserve keeper over Buttler, but I guess they'll select Buttler.
Bowling will just be all the guys who've played over the last year minus 1 or 2, + Crane. Say Broad, Anderson, Woakes, TRJ, Wood, Finn/Ball, Stokes, Ali, Crane
Can't see anyone from outside like Coverton getting past Finn/Ball. Bayliss wasn't exactly effusive about TRJ yesterday and kinda dismissed the impact he could have in Aus - so whilst he will make the squad, I can't see him playing unless he does really well in tour games.
Batting is most up in the air. I'd take Ballance to bat 5 (although Malan has begin to show some improvement imo). Stoneman (and Malan) I think will go. Backup opener likely to be Hameed/Hales. Maybe room for one surprise/random pick in the batting.
Best guess is Cook, Stoneman, Root, (2 out of Hales, Ballance and Hameed), Malan, Stokes, Bairstow, Ali, Anderson, Broad, Woakes, TRJ, Wood, Finn, Crane, Buttler
