Doncaster Rovers boss Paul Dickov claimed he was always confident his side would make the breakthrough in a one-sided South Yorkshire derby.
But despite dominating they had to wait until the 84th minute before clinching a 1-0 win with a wonder goal from substitute Harry Forrester.Dickov said: "We missed a fair few opportunities and left it late, but I always thought we would get the goal our play deserved.
"I've got a lot of belief in my players to keep going to the end and they justified that faith.
"I'm pleased with the character of the team and delighted with the result because that's five unbeaten in the league now and it keeps the momentum going.
"We always preach that if you can't win it's important not to lose, but we've drawn too many games we should have won so it was vital to get a victory.
"It took a special goal to settle the game because we had missed far easier chances to score.
"But Harry Forrester is well capable of scoring special goals because he's a special player."
