Retired fullback Chris Paterson has backed Scotland chief executive Mark Dodson's plan for Scotland to target winning the Rugby World Cup in 2015.

Scotland have revealed that they have a four-year strategic plan which includes the targets of winning a Six Nations Grand Slam and the Rugby World Cup in 2015.

Former Scotland fullback Paterson says it is not an impossible goal for Scotland who have just toured the Southern Hemisphere and were unbeaten.

"It's an ambitious target, but I think it's good to set ambitious goals," Paterson told BBC Scotland.

"International rugby is so close, so why wouldn't it be do-able?"

Scotland failed to win a match this year in the Six Nations but bounced back from the disappointment by beating Australia, Fiji and Samoa on tour

"We've seen Scotland win three games on tour over the last three weeks and international rugby is so close that could have been zero wins out of three," said Paterson, who retired to join the national coaching structure.

"And, if you turn that on its head, in the Six Nations, Scotland won zero out of five, and certainly the first three could have been wins against England, Wales and France.

"So you could have been going into the last two games against Ireland and Italy looking for two wins for a Grand Slam. "

"The margins are so, so fine in international rugby and, if you get the small bits right, there's no reason why you can't be successful."

The three victories on tour moved Scotland up from 12th to 9th place in the International Rugby rankings.
