"Could Gamboa be playing as he speaks Spanish! Can hear the shouts from Barca players."
"I think Celtic won't get a hiding but they are no Dundee United at the Nou Camp either. Still 2 wins behind the Arabs there."
In case you were unaware, this is the only match happening in Group C this evening.
Manchester City's match against Borussia Monchengladbach has been postponed due to adverse weather conditions.
Barcelona v Celtic (KO 19:45)
The teams are in the tunnel and ready to step on to the hallowed Camp Nou turf.
A few nerves will be jangling I'd imagine, and in the Celtic side too!
Barcelona v Celtic (KO 19:45)
"We have to be brave enough to come and play. We've got the team organised to defend well but also we've got speed and pace to counter-attack which is important on a big pitch like it is here.
"Barcelona is normally set-up to face a 4-3-3 or 4-2-3-1. Very rarely do they come across a five.
"It's going to be extremely challenging but that's the beauty of it."
Celtic manager Brendan Rodgers on BT Sport

Cristian Gamboa has played two and a half games since last September. Into the team tonight for a sink-or-swim experience.
Brendan Rodgers showing huge faith in him.

"If there are deficiencies in Dorus de Vries's game it will show up tonight. The goalkeeper plus all the other players will need a remarkable performance.
"Who knows, they may get an opportunity from a set-piece. Will they be able to counter-attack this team? Pique is not the quickest, we know.
"It will be interesting to see where Scott Sinclair plays and Patrick Roberts. I think Patrick may tuck the line but I think Sinclair will come back in because they will have Busquets sitting in front. Busquets is not an Iniesta passer but he dictates the game also.
"The way they are set up, with Scott Brown and Nir Bitton sitting deeper, that area between Moussa Dembele and them will be critical, so I think Scott Sinclair will probably come in to that area and leave it to Kieran Tierney on the other side to deal with the wide area."

Some Messi-Suarez-Neymar numbers for you.
2014-15 season: a combined 122 goals and 55 assists.
2015-16 season: a combined 131 goals and 65 assists.
This season so far: a combined 7 goals and 3 assists.
Total: 260 goals and 123 assists.
That's verging on the obscene.

Former Celtic defender Charlie Mulgrew: "The pressure's off. To go out there with no pressure is great. You can just go and enjoy it. You know you're not going to see the ball for long spells, it's just about enjoying the occasion and trying to stop Barca from scoring, if I'm being honest, and trying to get one at the other end. There are nerves before the match but it's a different type of nerves. It's just enjoying the game and anything else is a bonus.It's more running spikes you need than a pair of fitba' boots."

Barcelona v Celtic (19:45)
As we have mentioned, Celtic have enjoyed some of their finest moments in European football against the mighty Barcelona.
However, their last visit to the Nou Camp was a painful one for the Scottish champions. In December 2013 Neil Lennon's men were on the wrong end of a 6-1 hiding, with Brazilian star Neymar helping himself to a hat-trick.
The bad news for Celtic fans is Neymar starts again this evening. The very bad news? He has Lionel Messi and Luis Suarez alongside him.

Here's who Brendan Rodgers has chosen to face the mighty Barcelona...
Barcelona v Celtic (19:45)
The Nou Camp looks magnificent ahead of Barca's match against the Scottish champions, Celtic. We have an hour until kick-off.
Barcelona v Celtic (19:45)
Barcelona XI: Ter Stegen, S Roberto, Pique, Umtiti, Alba, Rakitic, Gomes, Busquets, Suarez, Messi, Neymar.
That famous front three start together for the first time this season...
The back four is changed completely from the weekend.
The good news for Celtic? Andres Iniesta is only fit enough for the bench.
Barcelona v Celtic (19:45)
Celtic XI: De Vries, Gamboa, Lustig, Toure, Sviatchenko, Tierney, Roberts, Brown, Bitton, Sinclair, Dembele.
Two changes there, with Gamboa and Roberts in for Rogic and Forrest.
Barcelona v Celtic (19:45)
One thing is for sure, the home team will make a few alterations from the weekend.
Barcelona suffered a shock 2-1 home defeat to Alaves on Saturday, with Messi, Suarez, Iniesta and Alba on the bench and Pique given the day off.
Just for the record, the last time Barca lost two home games on the trot over 90 minutes was in 1998!
