Hussey further suggested that the England Cricket Board (ECB) could also analyze their county cricket system and check if it was helping to produce Test players.
"They are going to have to go back further and look at their county cricket system as well and say is that an environment where they can help produce Test players to play you know, against the likes of Cummins and Starc, who are bowling very quickly and are very skilled bowlers you know.

"Obviously they have been a bit unlucky with no Jofra Archer and couple of other little injuries along the way. Ben Stokes has had a very compromised preparation as well but you can try and make as many excuses as you want at the end of the day, the Australian team is much better than England at the moment", he further added.
England and Australia announced their playing XIs on Tuesday morning. Usman Khawaja made a comeback to the Australian side while Stuart Broad replaced Ollie Robinson in the visitor's XI. Both sides are scheduled to face each other once again in the fourth Ashes Test from January 5, in Sydney.
