The hosts are trying to test Celtic's right flank, but Neil Lennon's side are holding firm. Possession being coughed up by both sides in the opening 10 minutes with the match yet to settle...

James Forrest darts through midfield as Celtic break up a Rennes attack. The winger tries to play in Mohamed Elyounoussi but the pass is behind the on-loan Southampton star, who loses his footing and a Celtic counter-attack fizzles out.

Rennes, lively in possession in the opening minutes, are looking to test Celtic through the middle. An attack is brought to a halt by Celtic captain Scott Brown; a free kick to the hosts in midfield as they continue to probe for an opening.

The hosts test Celtic with a long diagonal ball but it bounces through to goalkeeper Fraser Forster.

We're under way in France.

Roazhon Park is rocking ahead of kick-off. Both sides make their way onto the lush surface - perfect conditions for European football on a sun-kissed Thursday evening.

Speaking to BT Sport, Celtic manager Neil Lennon said: “We have got good depth. The starting 11 have been playing well so we didn’t feel the need to change much.

"[I've told the players to] believe in yourselves and go and play. They are a good team but we know we can score and that we are a threat. We need to be pragmatic at times as well."

It’s case of ‘if it ain’t broke, don’t fix it’ for Celtic, who name exactly the same side which won in Hamilton at the weekend. Not the case for the hosts, though, who’ve dropped one of the star performers of the season to the bench for the visit of the Scottish champions. The 16-year-old Angolan Eduardo Camavinga, who’s hoping to get French citizenship soon, is joined on the sidelines by Jeremy Gelin and Theoson Siebatcheu from the goalless Breton derby draw with Brest, while Faitout Mouassa drops out altogether.

It’s a beautiful night in the heart of Brittany, there won’t be too many empty seats in the near-30,000 capacity Roazhon Park stadium and the 2,000 or so Celtic fans, as well as the Rennes ‘ultras’ on the other side of the park, are already in good voice.

Confident about a Celtic win? Roused at the prospect of a Rangers victory?

Will both Scottish sides get victories tonight? Tell us.. thumbs up for YES and thumbs down for NO.

Rennes head coach Julien Stephan: "They are a team who are usually in the Champions League and they have huge experience with many internationals. We know they can play in the air and they are very technical.

"They are a very, very good team and have technical players like [Callum] McGregor, [Ryan] Christie, [James] Forrest, just to mention a few. They are well balanced and we know how difficult it will be, but we are lucky to play at home and the supporters are going to play a big role in a potential win for us."

Celtic manager Neil Lennon: We're not expecting to have the bulk of possession, which we normally have. Rennes are excellent on the ball and use the 3-5-2 system very well. They've had some stellar results already this season - they've beaten PSG and sit second in Ligue 1, so we've given this game quite a bit of thought over the last few days and worked on a few things. The players are ready."

To beat Paris Saint-Germain once - Neymar, Mbappe, Cavani et al - is good enough and to do so in the French Cup final is all the more commendable.

To beat them twice within a few months is surely more than coincidence. Rennes are no flash in the pan. They have been steadily improving over the past couple of years and, even though they've sold a few of their top players since lifting the national cup for only the third time, there is still plenty of talent left in Julien Stephan's side to worry Celtic.

Clement Grenier: The 28-year-old French playmaker is the man on whom Rennes rely creatively. Much of their good work either starts with him or flows through him. He made his name at Lyon, and also had a loan spell at Roma, and, if Celtic keep him quiet, they could put a real spanner in the works at Roazhon Park.

Eduardo Camavinga: Another key element in the Rennes midfield is the 16-year-old from Angola. He is already being tipped as the next Kylian Mbappe, not because he's a goalscoring sensation - that's not his game - but because he has maturity way beyond his years. Just ask PSG. Camavinga put his stamp all over them in last month's 2-1 win at the Roazhon with a display that provided an assist for the winning goal and had European scouts frothing at the mouth.

Celtic manager Neil Lennon names an unchanged starting XI to that which face Hamilton Accies in the Premiership last weekend.

It means a European debut in Celtic colours for on-loan Southampton winger Mohamed Elyounoussi.
