Mooooore?

And off we go! Parkhead is absolutely jumping!

Diagonal handshakes are exchanged - get you right here, I can tell you.

And out they come. Good of Messi to come out of hibernation for the occasion.

Parkhead does look warm, though - even if, in my opinion, it is less raucous and not as good a ground as Ibrox Stadium, by far the most intimidating venue I've visited. Anyway.

Wonder if this lad's there.

You'll Never Walk Alone time. Not tune.

Huge tune.

A word of warning: I am absolutely gazprommed up to the eyeballs tonight, so please bear with me.

FAO lovers of liberty...

Things they never thought they'd say: I'm looking forward to watching Scott Sinclair tonight. And Moussa Dembele, who looks a real talent, even if one not quite up there with Ousmane, who looks like a world-beater.

Celtic, meanwhile, are in a pickle. They're going to need at least three points from tonight and City away to get to the Europa League - and that's without Gladbach doing anything.

Permutations, then. Let's permute:

If Barcelona win, they qualify - as group winners, unless City beat Gladbach, and in which case top-spot will be decided on the ifnal day.

If Barcelona draw, they qualify unless Gladbach beat City.

If Barcelona lose, they still qualify unless Gladbach beat City, and if that happens, they'll need a draw in their final game.

And Barcelona:

So, Celtic line-up as follows. I imagine Brendan is employing a revolutionary midfield septagon tonight.

More indeed. And an exceedingly high level of more too.
