London - Australia coach Darren Lehmann has warned his under-achieving stars that no-one is safe from the axe ahead of the must-win third Ashes Test.
With the Ashes in danger of slipping away, Lehmann will use the three-day tour match against Sussex at Hove, starting on Friday, to look at potential changes to the team for the third Test.
"I'm not ruling anything out.
"Ashton (Agar) is a bit sore and I don't think he will play in Sussex so Nathan Lyon will play obviously.
"We had two guys get to 50 at Lord's but 50 isn't going to get us to where we need to go.
"Whether he will be fit for Old Trafford...he'd be in doubt," Gooch said.
However, asked if Somerset's Nick Compton – dropped ahead of the Ashes to allow Root to open in his place alongside England captain Alastair Cook – was the most likely candidate, Gooch added: "I'm not a selector, so I couldn't give you an indication to whether he would be the next cab off the rank or not."
