Rangers striker Kenny Miller acknowledged Sunday's defeat of Old Firm rivals Celtic represented "a huge step" in their quest to defend their Clydesdale Bank Premier League title.
The Light Blues lead their Old Firm rivals by 10 points, with a game in hand, after Maurice Edu's injury-time goal gave them a 1-0 victory.
"We've fought until the end and taken a huge step now to retaining the title," said Miller
Celtic skipper Scott Brown was shown a straight red card by referee Dougie McDonald in the 65th minute after wrestling with Gers' Kyle Lafferty, who escaped unpunished.
"With 10 men we thought we could get a winner but you've got to fight until the 93rd or 94th minute," added Miller.
"It's a great time to score - it's always going to be hard to come back after that."
As for the title race, Miller added on Sky Sports 1: "It's in our hands and has been for long time.
"It was an opportunity for them to beat us and pull the gap back to four points but we've increased the lead and we're delighted."
Edu added: "We thought it would be hard and it was a big game for us but there are still lot of games to go. We're just taking one game at a time."
On a personal level, the American added: "It's been great to get some games under my belt and getting a goal will spur me on to find top form."
