Danny Cipriani must oust George Ford and Owen Farrell to reignite his England career.
Eddie Jones omitted Cipriani from England's training camp squad and the Elite Player Squad (EPS) on Friday, then challenged the Wasps playmaker to raise his performance levels.
Cipriani won the last of his 14 England caps in August 2015 and has not featured at all under head coach Jones.
Now Australian boss Jones has admitted he does not consider the 28-year-old as a back-up squad option, after promoting Saracens' 23-year-old Alex Lozowski into his 45-man EPS.
"I had a number of difficult conversations yesterday," said Jones of informing a host of players they had been overlooked for selection.
"Danny knows what he's got to do.
"Look he's a talented player but I said it quite clearly to him. At the moment he's not one or two in England in terms of stand-offs.
"We see George (Ford) and Owen (Farrell) together as one and two. They are 23 and 24 years old, they are the heart of the England side.
"They can organise the team, they are tactically smart.
"So for Cipriani to get into the squad he's got to be able to show he can be number one."

New Zealand all but secured the Rugby Championship crown as they dominated the second half on their way to a comfortable 41-13 victory over South Africa in Christchurch.
The All Blacks made it four wins out of four as they outscored the Springboks 26-3 after the break, and will now win the tournament barring a bonus-point victory for Argentina against Australia later on Saturday.

Rob Howley has been named as Wales head coach while Warren Gatland concentrates on his New Zealand tour role with the British and Irish Lions for the next 10 months.
Howley, a long-term Wales assistant coach under Gatland, will take up the role and have what the Welsh Rugby Union announced as "full responsibility" for the senior team with immediate effect. The season features four autumn Tests and a Six Nations campaign.
It is a reprise of the 2012-13 season when Gatland headed up the Lions tour of Australia. Under Howley, Wales lost all of their autumn games that campaign, but recovered impressively to win the Six Nations title.
Lions boss Gatland has been seconded from his WRU role until after the New Zealand tour ends next July.
Michael Kearney will step down from his role as team manager after Ireland's November Test series.
Kearney took over the role from Paul McNaughton in January 2012, but is stepping back to allow the Irish Rugby Football Union (IRFU) plenty of time to plan for the 2019 World Cup.
"It has been a great privilege to work with the national team for the past five years," said Kearney.
"I've witnessed at first hand the incredible work ethic of players and management and the desire to reach world-class standards in everything they do.
"The time was right for me to step down and allow the next team manager time to integrate into the group ahead of the next World Cup."
Kearney managed Ireland on the 2013 tour to North America before remaining in the role under head coach Joe Schmidt.

England backs Jonathan Joseph and Anthony Watson have signed new contracts with Bath that will keep them at the Aviva Premiership club until 2019.
Both players, who were present throughout this year's Grand Slam triumph and the 3-0 series whitewash of Australia, left London Irish for the Recreation Ground in 2013.
"Jonathan and Anthony are exceptionally talented and since gaining greater international experience, they are having much more of a positive effect on the group - on and off the pitch," Bath first-team coach Toby Booth said.
