Jones was cool on the international prospects of Sale’s Danny Cipriani, whom he described as “a long way away” from an England recall.
The 28-year-old fly-half, who last week announced he will rejoin Wasps next season, made his England debut in 2008 but has only amassed 14 caps.
“Danny needs to play well. There’s no use talking to the press about it. You’ve got to dominate club rugby and show all the skills of a Test player,” Jones said.
“He’s not good enough to be in the squad at the moment. We have two outstanding 10s in Owen Farrell and George Ford.
“To beat those two, Danny has a long way to go, but he’s a capable player. It’s a matter of how hard he wants to work at his game.”
Jones also issued a warning to aspiring England players of the standards needed to catch his eye.
“This isn’t a kindergarten class,” he said. “If you want to play Test rugby, they have to keep me interested.
“I don’t have to keep them interested. Why should I keep them interested?
“Their game has to be so outstanding that I am saying, ‘Goodness me, I’ve got to get that guy in the squad.'”
