However, he warned England’s gameplan must change if they are to become the first nation to win back-to-back tournaments by beating South Africa in the final in Paris on Saturday.

“England have played smart and played to their strengths,” Mortlock said.

“Their tactics have been pretty consistent the last three times and I wouldn’t think they would change too much.

“They have had a lot of knockers, especially during this World Cup operation, and I think they have proved them all wrong by continuing to win.

“Try-scoring opportunities have been hard to come by and decisions have had a big impact on the results, so they have played smart and that’s why they are in the GF (grand final).”

But Mortlock warned England that their simple but effective gameplan will not be enough to knock over the Springboks.

“South Africa have the ability to overcome those tactics,” he said.

“I can’t go past South Africa. They have got a quality team, playing some good footy.

“It will be very tight but I’d say they will come out the winner.”
