Celtic hearts were broken by an injury-time winner from Barcelona's Jordi Alba, which earned the hosts a 2-1 triumph.

The Hoops claimed a stunning lead midway through the opening period, Javier Mascherano heading into his own net under pressure from Georgios Samaras.

However, they were unable to hold on until half-time as, seconds before the break,

Andres Iniesta finished smartly inside the area.

Hoops goalkeeper Fraser Forster made a string of terrific saves, before Alba's late breakthrough.
