Barcelona needed a second-half goal from Cesc Fabregas to claim a narrow 1-0 Champions League win over 10-man Celtic in Glasgow on Tuesday that leaves the Catalans top of Group H.
.
The Spanish champions dominated possession but failed to test goalkeeper Fraser Forster in the opening 45 minutes with Celtic's Georgios Samaras having the best chance of the half.
.
But it was a moment of madness from skipper Scott Brown that cost Celtic dearly as the midfielder was shown a straight red card in the 59th minute as he appeared to direct a sly kick at Neymar after tripping the Brazilian superstar.
.
However, Celtic recovered well from Brown's dismissal and substitute James Forrest forced Victor Valdes into a fine save before Charlie Mulgrew headed just wide.
