Falkirk manager Steven Pressley is convinced they can shock Celtic today.
With Celtic still hurting from last Sunday's injury-time defeat at Ibrox, which extended Rangers' lead at the top of the Clydesdale Bank Premier League into double figures, the Hoops travel to Falkirk knowing anything less than a victory is unacceptable.
"The pressure is very much on Celtic," Pressley said. "They are on the back of a disappointing result against Rangers and their supporters will demand the correct reaction.
"Everyone outside our own camp will be expecting a Celtic win but we're looking forward to the challenge.
"On two occasions this season we have played against them and taken points and we're looking to go one stage further.
"We'll work towards our game plan and hopefully we can put it into practice.
"Our sole concentration will be on our own preparation and how we go about the game. Our focus is on winning the game and not anything else."
