England head coach Eddie Jones is not guaranteed to keep his job for next year's World Cup in Japan despite having the support of the Rugby Football Union, RFU chairman Andy Cosslett has said.
Jones, who has been criticised for his management style and a rigid game-plan, oversaw a 25-10 consolation victory in the three-test series against South Africa on Saturday, ending England's five-match winless run.
While Coslett said that Jones "is still the man" in the eyes of the RFU, he stopped short of backing the coach for Rugby World Cup 2019, which takes place in 15 months' time.
"We have shown a lot of confidence in Eddie and we think he is still the man, but we will see where it goes to from here in terms of the next few months," said Coslett
"You're asking for unconditional support and only my children get that. It's not something you give because you're under assessment the whole time. And even then not always!
"We're very pleased with Saturday's result but we keep a balanced view because we've had a disappointing run before that."
The Australian, whose contract runs till January 2021, will be asked to present his case in a post-tour review conducted by the RFU's chief executive Steve Brown.
England will face the Springboks again at Twickenham on Nov. 3, followed by matches against New Zealand, Japan and Australia.
