"I thought both teams were trying to win the game, Carlisle gave as good as they got in the first half but we stepped it up a gear in the second half," said Laws after the match.
"Carlisle worked very hard for Roddy Collins, they got bodies behind the ball and earned themselves a draw.
"Both teams wanted to win for financial reasons and it wasn't to be for us today. That is the first goaless draw we've had this season so it shows we've been scoring goals.
"We will have to go to Carlisle with the same desire and determination to get through to the next round"
Carlisle United chairman John Courtenay exclusively told Iron-Bru.net yesterday that he was confident that his side would triumph if the tie went to a replay.
