Former Celtic manager Gordon Strachan suggests that Neil Lennon's team will need to go to a church and pray if they want to beat Barcelona.
The Bhoys meet the Catalan giants in the Champions League this season with the first meeting at the Nou Camp on October 23 with Strachan indicating that it is going to be a huge task to take points off Tito Vilanova's men.
"Well, you visit a church or chapel - whatever your preference is - and just hope," he said.
"Everybody has tried to take Barcelona on and they've all tried different systems.
"But trust me - it's good players who make the difference.
"Good men win games. There were about seven different styles at the Euro Championships in the summer but who ended up winning it? The best players, Spain.
"When we played Barca in 2008, that was when everyone in Britain realised this was a special team."
