Celtic maintained a two point lead over Rangers at the top of the SPL with a 0-0 home draw. Rangers boss Walter Smith felt they were due a penalty when Kenny Miller was clattered by Celtic skipper Stephen McManus.

"Kenny Miller had an attempt at goal and it was a late challenge," Smith said.

"If it happens in any other area of the pitch then the referee gives the foul.

"If it is in the penalty area then he has a couple of decisions to make and obviously he chose not to make them.

"As I say, Kenny had shot past and it was a late challenge but we never got it.

"But we had a couple of other opportunities that Artur Boruc saved."

"It was one of the poorest first-half performances that we've had away from home this season," Smith said.

"We didn't play well, the possession was poor and they had the one opportunity with Scott McDonald.

"We had the better of the second half but anything we produced, Artur Boruc was equal to it.

"But if you come to Celtic Park and Celtic only have a Shunsuke Nakamura free-kick as their only real attempt on goal, then your team are doing something right."

Celtic boss Gordon Strachan felt his side were the best in the first half and Rangers were better after the break.

The Hoops boss, however, was glad to see Boruc back on form.

"He didn't have too much to do but he had two smashing saves," Strachan said.

"He had a spring in his step and he made saves that he had been making for a long time. I liked what I saw."

Strachan was pleased at keeping the two-point lead over Rangers at the top of the League.

He said: "I would have been even happier if I was five points clear but I don't blame anyone bar ourselves.

"We have had a couple of opportunities in recent weeks to keep our seven-point lead but we didn't do well enough to do that.

"We kept the ball well in the first half but changed in the second half without knowing.

"We chucked Aiden and Georgios (Samaras) on but that changed the game to (Rangers') benefit.

"It had nothing to do with the two lads that went on, but the shape went and it gave them more chance on the counter-attack."
