Hard to see that Starc will be coming back. Don't see Aussie bowlers finding it difficult to bowl to English batsman. I think current bowling attack is quite good enough.
Addition of Jofra Archer to England side for the next is something interesting. He had very good figures in WC and delivered when needed and with current situation where England are behind in series it will be good to see how much his addition to the team will work out.
Strac needs to come back into the Australian team because he has a lot of fire power compared to say Siddle. Strac can change a match in just one bowling spell where as Siddle can't so Strac needs to come back in. Also I think Warner gets another chance but if he fails in this test match, the selectors will need to take another look at playing Finch. Its going to be an interesting test match to see if England can fight back and get a win to square up the series.
