Hadden has won three matches in his first Six Nations

"To step up and come to a place as intimidating as this and get the win is fantastic," he told BBC Sport.

"It was great to get the wins over France and England but this was the most important match for us. It shows how much we've come on.

"It wasn't pretty at times but I thought we were always in control and deserved the win."

Berbizier wants improvement

Chris Paterson was Scotland's hero, slotting over a 40-metre penalty three minutes from time to secure the 13-10 victory.

But Hadden paid tribute to the continuing progress of the home side, who once again made life difficult for the visitors at the compact Stadio Flaminio in Rome.

"I said this week they'd played better than us this season so we knew it would be tough," he added.

"Although some of our attacking play was a bit rusty, because we haven't really done much in the past two games, I thought the ambition and build-up was good.

"That's important because there's no doubt that our attacking play is a work in progress.

"I'd like to also pay tribute to the work Alan Tait has done because the defence was once again excellent and also full marks to Shade Munro (forwards coach) for the work done with the line-out because a week is not a long time to turn that around.

"I'd every confidence that we could produce the goods and I thought the line-out was first-class.

"I'm delighted with the quality of the coaching staff that I've got and I'm also delighted with the quality of the squad that I've got."
