England head coach Eddie Jones has insisted the best is yet to come from boy wonder George Ford.
The Bath fly-half has cemented his place in the England set-up with starting roles in the recent Six Nations victories over Scotland and Italy, but he has at times struggled to regain the form that saw him named the Premiership's player of the year last season.
Jones, however, has given Ford his backing and suggested the stand-off is still some three or four years from producing his best rugby.
"George is 22, but he looks 15," Jones said. "He's 22 and he has played 19 Tests. He's just finding his feet. He'll be at his best when he is 25 or 26.
"He's got talent, an exceptional pass, good vision and a good kicking game. The consistency of a Test 10 is not going to come at 23, it's going to come later down the track.
"George is a master player in progress. He will have ups and downs. Jonny Wilkinson had his first game at 18 and soon after got beaten 76-0. If you watched him in that game, you'd never pick him again."
