CAPTAIN Victor Matfield has demanded that his South Africa side keep their foot to the floor as they chase "the perfect game" against Wales in the second Test, writes Chris Kirwan.

The Springboks take to the field in Nelspruit on the back of a comfortable, five-try 38-16 success in Durban.

They were better in all facets of the game but legendary lock Matfield, who becomes South Africa's most capped player today, wants more.

"We had a look at last week's game and while it was a great win for us, we still made far too many mistakes," said the 37-year-old.

"In the first half we came close to meeting the targets we set ourselves and we only conceded one penalty before half-time.

"However, in the second half we gave away too much ball through errors and as I said before last week's game, the Welsh are a team that holds onto the ball for long periods once they have it. We don't want to give them ball to play with."

Had South Africa been at their most ruthless then it would have been an even bigger drubbing for Warren Gatland's side, who trailed 28-9 at the break.

"It wasn't a case of us sitting back after building up that big lead, we did want to score more tries, but sometimes we tried to force it too much," said Matfield.

"We have to have patience with ball in hand and go through the processes if we want to score tries. In the second half we got that wrong.

"What we are looking for is an 80-minute, clinical performance. We need to go out there and build an innings, ensure that we get all our plays right, whether it be on attack or defence, and then we will be moving towards the perfect game.

"That is a hard thing to achieve, but it is good to chase it. If we go out there and win the set-pieces, win the collisions and hold onto the ball, then the result should come.

"The Welsh might be better this week, but that is not an issue for us, we don't worry about the opposition. Our aim is for us to be better than we were last time out and to continue to improve."
