Celtic 2 Barcelona 1: match report Celtic had put in their work on the training ground. Charlie Mulgrew's delivery was pitched perfectly beyond the back post and Victor Wanyama timed his run perfectly to beat Alex Song to the punch and head sweetly past Victor Valdes. The priority for Celtic was to preserve their lead to the distant interval, a feat that had eluded them in Catalonia, where Iniesta equalised just before the break. But Barcelona refused to yield the ball and there were two heart stopping moments. One came when Dani Alves crossed for Alexis Sánchez to cushion a header beautifully across Forster but the ball skipped off the far post and out. The other was a Jordi Alba cutback bound for Messi's straining boot until Forster inserted a hand to divert and allow Kelvin Wilson to clear. Barca became increasingly frantic following the break but a world class Forster stop thwarted Messi and it was the goalkeeper who got the assist, with a kick from hand, when Watt left Mascherano for dead to finish perfectly and ensure a victory which could not be diverted even by Messi's strike in stoppage time as the skies over the east end of Glasgow boomed to the Hoops" euphoric anthems.
