England star back row Billy Vunipola believes the British & Irish Lions would have beaten the All Blacks 3-0 if Eddie Jones was in charge.

Warren Gatland and Rob Howley have come under stinging criticism from Sean O'Brien, who claims the team over-trained ahead of the first and third Tests while attack coach Howley was not able to implement his ideas leaving Owen Farrell and Johnny Sexton to 'drive it.'

Vunipola was initially named in the Lions squad but withdrew before they departed for New Zealand to fix a niggling shoulder injury.

"I wasn't there on tour but I guess if he [O'Brien] is saying it and the authority he said it with, he's probably right," Vunipola told the BBC.

"For me to sit here and say the Lions would have probably won is wrong. But personally my opinion is that if Eddie Jones went as coach they would have won 3-0. He is that good.

"I don't know how he would have done it, but Eddie would have found a way. Eddie has changed our mindset at England from always accepting we can't always be too outspoken and confident and he's really helped us kick on."
