"Gregan was fantastic", Jones told reporters.
Asked how England can fix the schisms Jones perceives to have formed, he added: "Having strong leadership definitely helps - having a leader who can unite groups". The Saracens' fly-half, who stepped into the breach against France, is leading his country for the first time over a sustained period in the absence of long-term captain, Dylan Hartley, whose ongoing problems with concussion have led Jones to wonder if he might ever play again. 'He demanded stuff from the team and they were frightened not to give it to him. He is a completely different character to Dylan. "Optus is a telecommunication company and their catchphrase was "yes", said Jones.
"You don't expect a captain immediately to be this all-conquering figure. It takes time, it takes effort and it takes patience", Jones added. They have different cultural backgrounds, Dylan from Rotorua, Owen from Wigan.
"They think about things differently, they look at things differently. Owen has got the job for five weeks in South Africa, to find his own team, to find his own style to influence the team and we will see how he goes".
Jones revealed he does not have a contingency plan in place if his defence coach, Paul Gustard, leaves to take up a position with Harlequins.
"If I dealt in rumours I'd be a nutcase and I'm close enough to that as it is, so..." I'm not a career development coach. "I appoint the best coaches I can find and then they work with me and we try to win games of rugby".
