And the 23-year-old Jackson, who plays his club rugby for Glasgow Warriors, admits that with competition for places tough all over the squad he will need to grab any opportunity to impress with both hands.

"Last season I put myself in a good position to try to get that number 10 jersey. Parksy's is going to put up a bit of a fight and he played very well against Italy - he's put down a bit of a marker,” he said.

"I've no idea what's going to happen for the first game, but once I get my chance I'm hopefully going to play well enough to take it."

“I presume there's going to be a number of changes for each game. Hopefully if I get my chance then I'll grab it.

"We've seen in previous World Cups that minor nations seem to perform way above expectations and really give quite a few teams scares.

"We know the games against Romania and Georgia are going to be another big Test match and we've got to be at our full capacity to put those teams away.

"Once we get into the Argentina and England games it's going to be another step up. Playing England in a World Cup is going to be pretty special."
