Tony Mowbray acknowledged that the league title can only be lost by Rangers following Celtic's 1-0 defeat at Ibrox. In an absorbing afternoon in Govan, Hoops captain Scott Brown was shown a straight red card by referee Dougie McDonald in the 65th minute after wrestling with Kyle Lafferty, but it looked as if the visitors would see the game out.
However, in the final seconds of three added minutes Edu, on earlier for Lee McCulloch, bundled the ball over the line following a goalmouth scramble to take Walter Smith's side ten points clear with a game in hand.
"As I have been saying for a few weeks, we have to keep going and try and win every game," the Celtic manager said. "But it's fair to say it's there for Rangers to lose. However, strange things have happened in football and so we have to win all our games starting next weekend.
"But we are all sensible enough to know that we need Rangers to slip up along the way, so we will wait and see. I thought we would see the game out, but it wasn't to be.
"We have been there before this season. A corner kick in the last minute of injury time, and the last opportunity and we lose a goal," he said. "Maybe that's the youthfulness of the defensive unit, but a lot of credit to them, they stuck to their task in difficult circumstances after the sending off."
Mowbray had not seen a replay of the Brown dismissal before he came in for the post-match press conference, but the Celtic manager denied he would have to exert a calming influence on Brown, whom he only recently made his captain. He said: "I'm not there to change Scott Brown from the combative footballer he is, that's what makes him the player he is.
"He hasn't got a case to answer with me, but we will wait and see. As I say, I will judge when I see (the replay)."
McDonald had also booked Rangers defender Madjid Bougherra and Hoops striker Marc-Antoine Fortune early in the game and then ruled out a goal by Edu for handball by his Ibrox team-mate Kenny Miller.
Injury to Rogne
Mowbray revealed that teenage defender Thomas Rogne, who was making his Old Firm debut, sustained a hamstring injury which caused him to be replaced by Darren O'Dea.
He said: "It was disappointing. We are suffering at the moment in that area of the pitch."
