Australia coach John Buchanan believes Adam Gilchrist's declaration has left the Headingley Test open for either side to win.

Gilchrist declared to leave England with 315 to win the Fourth Test, though bad light forced them off the field after facing only 2.3 overs with the score on 4-0.

Buchanan said: "Where the game is poised at the moment both sides have an opportunity to win.

"In the context of this game and the way the weather has been, both sides having that opportunity to win is a good scenario going into the last day on that wicket.

"We will continue to attack as long as we can. That will give them opportunities to score and us opportunities to take wickets, so it is a good contest and it should be an exciting last day."

But he did add: "We feel there will be sufficient chances tomorrow - at least ten - in which to take those wickets we need."

England batsman Mark Butcher emphasised the need for the home side to be positive in pursuit of victory, rather than try to bat out 90 overs.

"It is very important that you go out there with a positive attitude and look to try and win the game," said the England number three.

"If we do not manage that then of course we have to look to hang on, but if you go out there looking to draw a game at the outset you put yourself in difficulty which is not necessary."

England were criticised for their last-day defeat against Pakistan at Old Trafford this summer when many felt they played for a draw too early, having been set 370 for victory.

"These are a slightly different set of circumstances," said Butcher.

"But if you go out there basically looking to survive for 90 overs against that sort of bowling attack on a pitch offering a little bit of assistance you will get yourself into a little bit of trouble."
