Celtic are in high spirits at the moment.
After a scintillating start to the season culminating in a 5-1 demolition of Rangers in the Old Firm derby, the Bhoys now have the arduous task of taking on Barcelona in the opening game of this year's Champions League.
Nevertheless, Brendan Rodgers and his men will be confident they can try and cause an upset against the Catalans when they roll into town and pitch up at the Nou Camp if they can channel the performance of Saturday lunch-time into this game.
Rodgers saw a number of his players put in fine performances against Rangers and that was without star striker Leigh Griffiths so he'll be confident whoever he plays in the fixture will be up to the task.
We reckon the former Liverpool boss will go with this line up as he looks to shock the Blaugrana...
Dorus de Vries
The veteran goalkeeper will have more to do against Barcelona than Rangers but if he manages a clean-sheet Celtic will be sitting pretty.
Mikael Lustig
Lustig is charged with keeping Neymar quiet down Barcelona's left side and may fancy it after the Brazilian's lacklustre performance against Alaves at the weekend.
Erik Sviatchenko
Sviatchenko and Toure need to be firm at the back to keep Luis Suarez out but with their partnership so far looking strong they'll fancy their chances.
Kolo Toure
Toure has seen it all before in the Champions League so his experience on the pitch will be absolutely crucial. Simply has to start.
Kieran Tierney
How the young full-back does could give an inkling into his future but based on what he's done so far Rodgers will be confident he'll put in a solid performance.
Scott Brown
A lot of the Old Firm attention was on this man and Joey Barton but Brown simply walked that contest. He'll be up against the world's finest midfielders now, though, but he'll surely back himself to perform.
Nir Bitton
Bitton needs to remain disciplined in this game for Celtic to even stand a chance. If he does and he and Scott Brown are a tight unit then, who knows.
James Forrest
Celtic have to make use of any chance they get and that means Forrest will have to be on top of his game. They won't get to create too many but Forrest has the ability to make something.
Tom Rogic
Rogic is one of Celtic's most exciting players so if he can perform on this stage they have a chance. He has to get at the Barca defence as much as possible alongside the other two attacking midfielders.
Scott Sinclair
Sinclair has been a revelation since joining in the Summer and it's games like this that made him sign.
He has the pace to give Barcelona problems so could be the one to watch.
Moussa Dembele
With Griffiths out many wondered how Dembele would do in the Old Firm and he duly delivered a hat-trick. Deserves to keep his place against Barca and another three goals would be more than welcome.
