Neil Lennon has described as "nonsense" claims by Rangers boss Walter Smith that a campaign based on claiming for decisions and penalties led to Celtic's spot kick award at Ibrox.
There were less than 10 minutes remaining when Hoops substitute Anthony Stokes, on for Gary Hooper, was adjudged by referee Craig Thomson to have been fouled by Light Blues' midfielder Steven Davis inside the box.
Allan McGregor made a great save from Georgios Samaras to keep the game goalless and Rangers a point clear at the top of the Clydesdale Bank Premier League, although the title pendulum seems to have swung towards the east end of Glasgow as Celtic have a game in hand.
However, the Celtic boss was short and sharp when told what his Ibrox counterpart had said. "It is nonsense," he said. "Absolute nonsense.
"Have they not had penalties against us this season, one where the referee wasn't even looking at it? Eh?
"Where is his argument there? It looked a penalty to me. People are telling me it is soft but I think the one with (Joe) Ledley in the first half could have been one, and the second one with (Anthony) Stokes, they are telling me there was contact although he did go down a bit dramatically."
