Scotland coach Frank Hadden was in cautious mood on Sunday despite his team's 56-10 win with eight tries as a premium over Portugal in their first game of the World Cup on Sunday.

"It wasn't a tremendous performance", Hadden (pictured) said after the inconsistent display against the World Cup debutants.

"We are certainly expecting better in the next one, he added."We wanted to start with a win and tremendous credit to Portugal. They made it very difficult for us and full credit to them."

Scotland should have another easy ride when they play their second game of Pool C against Romania in Edinburgh on Sept. 18 before facing the All Blacks on Sept 23.

Their decisive game for second place and qualification for the quarter-finals against Italy, crushed by the All Blacks 76-14, on Saturday, will come on Sept. 29.

Hadden's Portuguese counterpart Tomaz Morais was ebullient after his team acquitted themselves with honour on their debut and even managed a first-half try when winger Pedro Carvalho scored.

"We played well in my opinion. Our players played with spirit and all the players played with courage," he said.

Portugal will face the ultimate test against the All Blacks in Lyon next Saturday but their great day could come when they will play a more experienced Romanian side on Sept. 25 in Toulouse.

"We are not afraid of New Zealand. We will play well against Italy and perhaps we will have a surprise against Romania," Morais said.

Portugal's captain and number eight Vasco Uva, who delivered a powerful display, said the match was an important step for the development of rugby in his country.

"We knew that it was going to be tough but we gave everything we had to this game. We knew Scotland would be hard, but it was a very good game and I think we showed just what Portuguese rugby is about," he said.

"We are expecting to see some of our guys in the professional championships in England and France. I think we are telling our country that there are other sports besides football."
