LUIS ENRIQUE, the Barcelona coach, has told his players to forget all about their seven goal defeat of Celtic because this evening’s match is going to be nothing like that stroll in the Nou Camp.

Indeed, Enrique feels this match may well resemble the classic 3-3 Celtic Park witnessed when Manchester City came to town because Brendan Rodgers and his players have learned from that chastening Catalan experience.

Lionel Messi is here and will line up alongside Neymar and Luis Suarez. Gerard Pique has shaken off a slight foot injury, so all the superstars, more or less, are available to him and when that happens this team do tend to blow away everyone.

Even if their domestic form of late has been unusually inconsistent – at least going by their astronomical standards.

A huge press pack follow Barcelona wherever they go. Every cough and spit is recorded. Even the most insignificant matter is debated for page after page.

It was obvious inside the No7 Lounge at Celtic Park that Enrique wasn’t really in the mood to interact with the travelling media circus; many of whom have been critical of his team in recent weeks.

However, when the subject of his opposition was raised, he warmed up ever so slightly and turned on the charm.

“It's going to be a different game than the Nou Camp,” said Enrique. “What happened in September is not a reference to what will happen in Glasgow. Celtic have changed their style since then.

"We have to be ready for everything from Celtic - high pressure or low pressure. But it's going to be a different story altogether from the last time. It's always good to score early and Celtic need points, so they will come out and at us.

"I haven't used any of the images of the game from the Camp Nou - because it won't be like that this time. It will possibly resemble more the game Celtic played against Manchester City. They will try to play the game in the same way they did that night.”

Messi will start. Sickness meant he missed the weekend’s match with Malaga, a poor 0-0 draw, which perhaps explained the frostiness between Barca hack and Barca coach.

The Argentine is, of course, not really human and therefore could be seen running about the pitch under the floodlights at Celtic Park looking the most healthy man alive.

Enrique said: “I only saw him this morning. It was not the best condition to assess whether he will play. However, Leo is always ready to play. I am sure tomorrow he will be ready. He is 100% and eager to give the best version of himself.”

Although he would not say if the world’s best player was on his way to Manchester City. That got a terse he didn't know.

There has been something of a love-in between the two clubs in recent years when they have met one another regularly in this competition.

Celtic have largely done well at home, the ‘Tony Watt game’ the obvious example, and even those defeats in Glasgow have carried with them a touch of misfortune if you couldn’t really say Barcelona didn’t deserve to win.

A big factor in the Manchester City match, something which was utterly absent when Borussia Monchengladbach came to town, was that Celtic began really well and that injected extra life into an already frenzied crowd.

It is a tad more tricky to roar on your team when they are getting passed off the park.

What Brendan Rodgers has to do, and boy is this easier to say than do, is make Barcelona go backwards. Do that and Parkhead will be jumping.

“Of course this is a great place,” said Enrique. “This is a great stadium - one of the best in Europe. This is where any player wants to play in front of these fans.

"Celtic have great supporters. They are one of the best examples in football. They have a big support that follow them home and away and they travelled to the Nou Camp earlier this season. Football is about enjoyment and the Celtic supporters have that.

"I will tell my players to enjoy it and if they do then we will get to the next round. Winning is always important and that's what we aim to do.

Rafinha, the Brazilian midfielder, is perhaps the least charismatic footballer to ever have spoken into a microphone but his message was clear enough.

“This is a really important game, especially after the weekend,” he said. “It’s going to be complicated here in Glasgow. Celtic are going to try to show their worth and it will be a tough game. If we do win, it will ensure that we get to the next round of the Champions League and that was what our aim is.”
