Celtic and Barcelona have played out a goalless first half at Celtic Park in their Champions League Group H clash.
Visitors Barca controlled possession and made the attacking moves in the opening minutes of the encounter, but good work in defence especially from Efe Ambrose kept the Spanish champions out.
Neil Lennon's side continued to frustrate Barcelona as the half wore on and restricted them from finding the final pass that would result in a goal.
However, it was Ambrose again who cleared the ball in the nick of time after Pedro had drilled a dangerous cross into the box on 33 minutes.
Five minutes from the interval Neymar went close for the Catalan giants when he tried to turn in a cross from Daniel Alves, but failed to find the target.
