That brings to a close another incredible night of action here on Bleacher Report, where I hope you've enjoyed the commentary—though, if you're a Barcelona fan, presumably not the result so much.

There's still plenty more reaction and analysis of the entire spectrum of Champions League results to come here on B/R—including late wins for Chelsea and Manchester United—so check out the site over the next couple of hours.

I'll be back again tomorrow night with coverage of the Europa League tie between Anzhi Makhachkala and Liverpool so make sure you tune in for that.

Until then, thanks very much and good night!

What an incredible result in the Champions League, and Celtic fans, players and manager alike are indescribably delighted.

That result has put Celtic up to seven points in the Group, two behind Barcelona but far more importantly, three points ahead of the nearest challenger.

Benfica have beaten Spartak Moscow in the other match in this group, leaving those two teams on four and three points respectively.

FULL TIME AT CELTIC PARK!!!!

CELTIC 2 BARCELONA 1

90+3'—That might be the last chance. Pedro gets past Ambrose down the left but runs the ball out for a goal kick. Celtic clear downfield...

90+2'—Madness. Celtic leave the ball to run out of play but Messi keeps it alive, hooking the ball into the area but nobody can get onto it. Almost suicide stuff. 

Barcelona have a goal back. Quick passes in the box lead to a shot from Cesc which is again really well saved by Forster, but Messi is on the rebound and plants the shot high into the roof of the net. Three minutes of added time remaining!

GOOOOOAAAAALLLLL!!!!!!

Celtic 2 Barcelona 1

Leo Messi, 90 mins

Four minutes of added time to be played.

89'—CHANCE! David Villa has probably scored here with his first time effort—if his own teammate, Gerard Pique, is not standing in the way. He is though, and the ball is blocked behind for a corner.

88'—Iniesta curls a shot at goal from the edge of the area, but it's tame and easily saved by Forster.

86'—Mere minutes remaining and still Celtic stand firm in defence. As Celtic break with another long pass Watt goes racing past Mascherano and crashes to ground—but it's the Celtic man who is pulling, and play continues.

Incredible stuff. Celtic have doubled their lead with just seven minutes remaining. A long kick upfield should be easily dealt with by Xavi as it bounces but he misses the ball completely and suddenly Watt is away, running through on goal and one on one with Valdes. He steadies himself, looks up and plants a fine finish beyond the goalkeeper. 2-0, Celtic in dreamland.

GOOOOAAAAAALLLLLLL!!!!!

Celtic 2 Barcelona 0

Tony Watt, 83 mins

82'—Or Messi. Anything suits Messi. He takes it and curls the ball over the wall, but Forster is on the move early and catches the ball well.

81'—Clumsy challenge from Ambrose who chops Andres Iniesta down just outside the box, on the left edge. It suits a right-footer if they are thinking of shooting.

80'—Into the final 10 minutes. Can Celtic keep holding out? So far they have ridden their luck at times, but worked extremely hard and defended well for long spells.

Celtic sub: Samaras off, Beram Kayal on.

77'—Alves' cross is curling and dangerous, but Celtic head half-clear. Alba hits the rebound on the volley—but it's blocked behind. The pressure is unending, constant, relentless...but constantly off target, too. After the corner, David Villa ends up curling the ball well over the bar and Celtic are getting closer.

76'—Space opens up suddenly for Andres Iniesta to line up a shot from 20 metres out, but he fails to get over the ball properly and his effort goes flying over the crossbar.

75'—Villa hasn't been able to get involved much since coming on, and he's unable to control just outside the box when the ball breaks for him. Fabregas gets into the area and cuts the ball back, but no Barcelona players are close enough to attack it.

73'—Barcelona still can't find a way through and we're almost into the final quarter of an hour. The rain is teeming down in Glasgow, but the home fans are still in fine fettle. Plenty of noise inside Celtic Park.

Celtic sub: Lustig goes off to be replaced by Tony Watt.

Double Barcelona sub: Gerard Pique and Cesc Fabregas come on for Bartra and Song.

69'—BRILLIANT SAVE! Forster again to the rescue, keeping Barcelona at bay single-handedly at the moment. Literally in this case, as he produces a stunning one-handed save from Messi's curling shot after Alba pulled the ball back.

67'—Alex Song is very lucky, and rather silly too. Already booked, he leaves a leg kicked into the back of Miku in a nothing challenge near the halfway line, concedes the free kick and is lucky not to be sent off.
