Davide Zappacosta is brought down by Vitaliy Mykolenko and Chelsea have a free-kick on the right wing.

ZOOOOM as Ruben Loftus-Cheek flies past a few defenders but he ends up checking back and does nothing with it.

Kiev's little spell is over - they've had 65.5% of the ball in this half compared to 26.3% in the first - and it's back to Chelsea possession now.

Now Kiev have the ball in the net but it's ruled out for offside. They're making a proper go of it to be fair.

Dynamo Kiev have sprung into life. Antonio Rudiger half-clears to Kiev captain Serhiy Sydorchuk. His first shot is saved by Kepa and his rebound hits the base of the post.

THEY'VE DONE IT! Dynamo Kiev have managed a shot on target for the first time in this tie. Volodymyr Shepelev rolls a 30-yard shot which Kepa could throw a hat onto. But they all count.

Just need another seven more - and for them all to go in.

Olivier Giroud leaves Vitaliy Mykolenko with a souvenir - an accidental elbow to the head.

Mykolenko is fine to continue though.

Chelsea on the goals hunt already in this half. But Kiev's defence holding firm for now.

Here we go again.

Tell you what, Maurizio Sarri loves that notebook of his. "Buy more cigarettes" he probably writes down.

Bradley Bicknell: Emlyn what are the odds of Dynamo Kiev winning 7-3?

Kiev are 1,000-1 odds to reach the next round now. They need to score seven (without conceding again).

Unai Emery makes just two changes to the Arsenal side who beat Manchester United 2-0 at the weekend.

Henrikh Mkhitaryan has to settle for a place on the bench but Alexandre Lacazette is in the starting line-up after his ban was reduced to two matches.

In comes keeper Petr Cech for Bernd Leno and Shkodran Mustafi replaces Sokratis. Lucas Torreira, who started the defeat at Rennes, is on the bench.

Arsenal XI: Cech, Mustafi, Koscielny, Monreal, Maitland-Niles, Kolasinac, Xhaka, Ramsey, Ozil, Lacazette, Aubameyang

There are two changes to the Rennes side who beat Arsenal 3-1 in the first leg.

Mehdi Zeffane and Adrien Hunou drop to the bench, while M'Baye Niang and Hamari Traore come into the team.

Goalscorers Ismaila Sarr and Benjamin Bourigeaud are also in the starting XI.

Rennes XI: Koubek, da Silva, Mexer, Sarr, Grenier, Niang, Bourigeaud, Bensebaini, Ben Arfa, Andre, Traore

Dynamo Kiev managed just one touch of the ball in the Chelsea penalty area in the first half.

Now who was it that said they needed a "miracle" to go through?

Ossie: Love watching Hudson-Odoi & Loftus-Cheek. Both have the ability to beat a man and are genuinely exciting to watch! Should be playing more games. I think this transfer ban might be a blessing in disguise for Chelsea. Let's build a team around Hudson-Odoi, Loftus-Cheek, Christensen, Tammy and Pulisic.

Shaun S: Giroud is better than Higuain, doesn't get the praise he deserves. Top player.

Still 45 minutes to go but this is all over.

One minute added on. Willian booed as he goes to take a corner. This cross is cleared.

Corner to Chelsea, won by Marcos Alonso. Willian to take. Headed wide by a defender for another corner.

Dynamo Kiev need to score six. They haven't had a shot on target in either leg.
