Miggmaester: Once again "Sarri-ball" is exposed for its naivety. A little pressing and everything goes to pot. Sorry but this is no way for a club like Chelsea to be playing a 2nd division equivalent.

Napoli 0-1 Arsenal
Arsenal are almost home and dry.
Petr Cech has been booked for time wasting - in truth he's had little to do all game.

Chelsea 4-3 Slavia Prague
Sighs of relief around Stamford Bridge as two-goal Petr Sevcík is replaced by former Chelsea winger Miroslav Stoch.
Sevcik is not going to forget this night in a hurry - his second goal was an absolute beauty.
Frankfurt overturn deficitpublished at 21:35 British Summer Time 18 April 2019
Image source, ReutersIt's all happening at Eintracht Frankfurt. They are 2-0 up now against Benfica and, as a result, leading on away goals. This is after losing the first leg 4-2 in Portugal (having been 4-1 down at one stage). Sebastian Rode with the latest goal.
No such worries for Valencia. They are 2-0 up against fellow Spanish side Villarreal - that leaves them 5-1 up on aggregate.

Another poor pass by Chelsea - this time by substitute Jorginho.
The home side are rattled - Emerson has joined N'Golo Kante in the ref's book.
Around 15 minutes left at Stamford Bridge.

Arsenal's travelling fans give Alexandre Lacazette a standing ovation. Alex Iwobi is sent on by Unai Emery.
This has been a thoroughly professional performance by the Gunners.

Pedro was superb in the first half - two goals and one assist.
He's just over-cooked a straightforward pass.
Groans from the home fans.
Chelsea are not helping themselves!

What has happened to Chelsea?
Their defence has crumbled and Petr Sevcik is on a hat-trick...but scuffs his shot and a golden chance is gone.
The mood at Stamford Bridge has completely changed.

Dan Wilcox: The @BBCSport, external in play update bloke wrote "this tie is done and dusted" and since then Chelsea have conceded twice in 10 minutes! Curse of the commentator comes to mind!
Me and my big mouth, Dan!

Two goals in three minutes for Slavia Prague.
Chelsea still lead 5-3 on aggregate but they're no longer coasting.
Another Slavia goal will make things VERY interesting.

Napoli 0-1 Arsenal
How did he miss? It's brilliant from Napoli goalkeeper Alex Meret but how did Pierre-Emerick Aubameyang not score there?
Alexandre Lacazette gets down the right and squares the ball to Aubameyang, in acres of space, seven yards out but Meret tips his shot over.

GOAL - Chelsea 4-3 Slavia Praguepublished at 21:12 British Summer Time 18 April 2019
Petr Sevcík
Incredible!
Slavia Prague were dead and buried at half-time but they're back in this.
It's a beauty from Petr Sevcík.
Moments after embarrassing Chelsea's keeper, he bends a beauty into the top corner from outside the penalty area.
The visitors are dreaming of a famous comeback!

Petr Sevcík
Kepa Arrizabalaga will not want to see that again!
The Chelsea keeper is beaten at his near post by Petr Sevcík's shot from distance.
It's a good strike by the Slavia man but a keeper who costs £71m should be doing better.
It's 5-2 on aggregate.

How long before Maurizio Sarri makes a change?
Eden Hazard, who was on the receiving end of some meaty challenges in the first half, is back out but this tie is done and dusted.
Callum Hudson-Odoi will be itching to get at this lot.
