46' The visitors are unbeaten in their last 47 games in all competitions when ahead at the break.
46' Both sides are back out and referee Kuipers gets the next 45 minutes of this Champions League game underway!
Chelsea will be looking to start the next 45 just as they did the first but with the added emphasis on being more clinical. If chances, such as the ones Werner and Mount missed, are passed up again, it could offer Stephan and Rennes a glimmer of hope of getting some thing out of this Champions League fixture.
After a fast start, Lampard's men took the lead through Hudson-Odoi's calm, slotted finish under Gomis, courtesy of Mount's wonderful initial throughball to the winger. Despite Rennes growing into the game, their only real chance so far came through Lea Siliki, who blazed his right-footed effort over the bar, meaning the hosts go in 1-0 down at the break.
45' + 2' HALF-TIME: RENNES 0-1 CHELSEA
45' + 1' Bourigeaud wanders up to the free-kick before whipping a right-footed into the wall and the ball deflects out for another corner to the French side.
45' Guirassy turns Silva as the striker looks to latch onto Da Silva's throughball and the Brazillian centre-back is forced to concede a foul in a great position, just outside of the visitors' area.
43' Rennes threaten from another corner as the hosts look the most likely of the sides to score next. This time, however, Bourigeaud is unfortunately caught offside from the second phase of play which offers the visitors a chance to regain possession and slow things down from their free-kick near the byline.
42' Bourigeaud's corner is met firmly by Da Silva, who climbs the highest at the back post, but the centre-back's powerful header is comfortably beaten away by goalkeeper Mendy.
41' Chilwell releases Guirassy with a poor pass backwards to Mendy. Luckily for the left-back, Silva shows his class and manages to deal with the danger as he gets back before hoofing towards the left-hand corner to offer the hosts another set-piece opportunity.
40' CHANCE! Chilwell gets far too tight to Doku, who beats the English left-back for pace comfortably before playing towards Bourigeaud. The move eventually finds Guirassy, who on the turn scuffs a right-footed effort towards the left-hand corner, however, Mendy is alert to the danger and saves with relative ease.
38' The visitors look to have broken Rennes' press until Nzonzi steps in, wins possession back for his side and plays towards Lea Siliki. However, none of this matters, as Lea Siliki's touch is lazy at best, which allows Azpilicueta to intervene.
36' Doku shows his speed as he races onto a flicked header, with Lea Siliki and Guirassy queuing up in the box, the right winger's cross is then poor and dealt with by Silva.
35' Mount and Werner exchange quick passes before looking to launch a counter-attack, however, the former's pass towards the German is weak and allows Nyamsi to intervene.
34' The hosts are screaming with their arms in the air once again as they disagree with another of Kuipers' decision, which all seems incredibly needless for a throw-in near the halfway line.
33' Abraham ducks down to win a header and manages to catch the tip of Traore's boot, winning a free-kick for the visitors in the process. Referee Kuipers has a quick word to explain his decision to the right-back before play resumes.
32' MISS! Doku beats Chilwell and Jorginho before crossing towards Bourigeaud, whose shot is deflected by Zouma into the path of Lea Siliki. The Rennes forward has just Mendy to beat but manages to blaze his right-footed effort over the bar from inside the area.
30' GREAT SAVE! Chilwell has two attempts at crossing from the byline with the second finding Mount in the six-yard area. Goalkeeper Gomis looks well out of position but remarkably manages to claw his right hand around Mount's poked right-footed effort and turn the shot away for a Chelsea corner.
28' The hosts' second corner comes again down the left and the same result comes as Mendy and Abraham combine to avert the danger, clearing long down the pitch.
27' Nzonzi releases Truffert with a diagonal pass before the full-back plays inwards towards Lea Siliki. Rennes then stall in possession, which allows the visitors to regroup and defend in numbers.
25' Hudson-Odoi's two Champions League goals have come in his last three appearances in the competition (9 appearances in total).
24' If results stay this way in Group E then Lampard's side will qualify for the next stage of the Champions League with two games to spare, which means he could rest players in the upcoming European games in order to protect his side from the hectic Premier League schedule.
20' Hudson-Odoi is far too enthusiastic as he looks to dispossess Truffert and referee Kuipers rightly awards the hosts a free-kick on the left-hand touchline.
19' Mount plays a lovely flick to himself but then his pass to Kovacic is poor as the Croatian looks to burst from midfield into the Rennes box.
17' Camavinga drops deep and attempts to orcherstrate the play, however, Gomis is then forced to go long and lose possession. The game has calmed down slightly after a frantic opening 10 minutes.
15' Rennes get their first corner of the game which Bourigeaud will take. The midfielder's right-footed set-piece evades all the players in the box as Mendy comes out to claim the ball.
14' Chelsea are looking to win three consecutive Champions League matches for the first time since December 2015, while they haven’t won three in a row without conceding since November 2013.
12' Chilwell is swamped by three Rennes shirts but remains calm, playing out from the back around the press until Abraham's poor touch allows the French team to regain possession.
10' Werner has acres of space down the left and is released by Jorginho but the German's touch is poor, which allows Traore to recover and eventually win a throw-in for the hosts.
9' A sharp start by Chelsea is halted as Kovacic slams into Lea Siliki near the centre circle, which offers the hosts both a free-kick and some form of respite.
8' The French side have hosted English teams twice previously in European competition and won both games, beating Aston Villa in July 2001 in the Intertoto Cup and Arsenal in March 2019 in the Europa League.
6' Hudson-Odoi again looks to make some thing happen down the right-hand side, this time winning a corner off of full-back Truffert. Rennes deal with the corner well and then look to break through Nzonzi.
5' OVER THE BAR! Hudson-Odoi puts it on a plate for Werner with a low, driven cross into the area with his right foot from near the right-hand touchline. However, with just the goalkeeper to beat inside the six-yard area, Werner somehow manages to sky his right-footed effort well over the bar. The German will not get a better chance than that all game.
4' Rennes immediately look set-up to be more 4-5-1 than 4-3-3 with Doku and Lea Siliki tucking in to negate the threat of Chelsea's full-backs.
3' Chilwell latches onto Werner's flighted pass over the right of the Rennes defence but the left full-back's volley is blocked before it can trouble Gomis' goal.
2' Mendy miscues his clearance but Bourigeaud cannot capitalise as the ball trickles out for a throw-in on the far side.
1' Referee Bjorn Kuipers blows his whistle to get this Champions League fixture started!
