England team director Andy Flower has refused to be drawn on his long-term future after his team surrendered the Ashes in Australia.
Defeat in the third Test in Perth left England facing an insurmountable 3-0 deficit in the five-match series.
That brought calls for changes to the team line-up, while speculation has also surrounded Flower himself.
The former Zimbabwe international has been in charge of the England team since 2009 but ceded control of the limited-overs sides to Ashley Giles last November and will not confirm whether he plans to stay beyond this series.
"I've got that judgement to make and the England (and Wales) Cricket Board will have that judgement to make as well," he said.
"I don't plan that far ahead, personally. Obviously my role means that I have to plan ahead for the team's sake but personally I don't like looking too far ahead.
"Frankly, there are still two Test matches to play in the series and I want all my focus to be on those two Test matches. I think that's the right thing to do for the England cricket side."
He did admit, however, that there is a chance of changes on the field.
Senior bowlers Graeme Swann and James Anderson and wicketkeeper-batsman Matt Prior are among those to have notably under-performed during England's defeats in Brisbane, Adelaide and Perth.
And Flower said: "We are going through a tough period as a side now and a number of those individuals have been going through tough periods in their careers.
"It doesn't mean that their careers are over but it does mean they need to call on that experience to help them get out of those tough times a little quicker than other people might."
Yorkshire's Jonny Bairstow would be the natural replacement should Prior be stood down and Flower said: "It's a possibility, of course.
"Matt Prior has been an outstanding cricketer for England during the second phase of his career but, like with all those positions, we constantly review what our best side will be, what will give us the best chance of winning.
"We have to have an eye to the future as well so we will meet over the next couple of days and start getting a little clarity on those decisions."
