London buses and all that. Chelsea's fourth effort on target as Olivier Giroud's header is tipped over by Denis Scherbitski.

Eden Hazard's game was longer than expected, but he's replaced by Willian after the hour-mark.
Bate Borisov 0-1 Chelsea
The ball comes into the box, a fully fit Eden Hazard blasts the ball home but this returning version lets the ball run across him, by the time he shoots it's easily saved.
That's their second shot on target.
And now a third as Ross Barkley's 25-yard drive is tipped around the post.
Bate Borisov 0-1 Chelsea
This is a huge chance for Bate to equalise, an even better chance than a minute ago. the ball is pulled back to Aleksey Rios, unmarked 12 yards out, and he blasts it well over the bar.

Bate hit the woodwork for a second time - this time it's Nikolai Signevich!

Have some faith in your striker Dexter...
Dexter: No offence, but with Giroud up front, we couldn't score even if we had a rugby-style goal to aim at. Too bad red-hot Morata is cooling off at Cobham...
Bate Borisov 0-1 Chelsea
Suspect we'll see Eden Hazard come off soon.

Tim: Looks like the Lampard/Gerrard debate is happening all over again at Chels - Barkley & Loftus-Cheek just not working

Chelsea are definitely through if they hold onto this win.
They will win the group if the other game - MOL Vidi v PAOK - remains goalless.
Olivier Giroud
Olivier Giroud scores his first goal of the season.
Emerson Palmieri puts in a good cross, which Giroud heads toward goal. Bate goalkeeper Denis Scherbitski gets a touch and should do better but the ball flies past him into the net.
That's Giroud's first goal under Maurizio Sarri - and Chelsea's first effort on target tonight.
Bate Borisov 0-0 Chelsea
Free-kick to Chelsea, Eden Hazard curls it past everyone from the corner of the box. Goal-kick.
Bate Borisov 0-0 Chelsea
Bate's Nikolai Signevich has to tie his laces. That's one of the most interesting moments of the game.
Bate Borisov 0-0 Chelsea
No changes at the break, Maurizio Sarri said Eden Hazard would only get 45 or 50 minutes. But maybe he thought they'd be winning by that stage.

A pretty accurate description of that first half...
