Falkirk 0 Celtic 3:Goals from Georgios Samaras, Koki Mizuno and Scott McDonald gave Celtic victory at Falkirk as the champions restored their lead over Rangers at the top of the Clydesdale Bank Premier League to four points.
Former Manchester City striker Samaras had missed a sitter just before the break but made up for it three minutes after the restart when he headed Scott McDonald's cross past Bairns goalkeeper Robert Olejnik.
In the 90th minute, Mizuno, making his first start for Celtic, took a pass from fellow Japanese midfielder Shunsuke Nakamura to slot past Olejnik and cap a fine performance.
In the third-minute of stoppage-time, from a suspiciously offside-looking position, McDonald rounded Olejnik before slamming in a third.
From Celtic's point of view, it was perfect preparation for next week's Old Firm clash at Ibrox.
Just after kick-off a section of the travelling support voiced their support for Republic of Ireland winger Aiden McGeady who had been suspended from the first team and fined two weeks' wages after a dressing-room bust-up with manager Gordon Strachan following the 1-1 draw with Hearts.
According to one report, McGeady apologised within 48 hours, but Strachan brushed off questions in the aftermath of the victory.
He said: "I think the internet have got that wrong again. It depends what internet you go to. We will keep it in-house."
