Matty Cash was praying that he just stepped up enough, when Ayoub El Kaabi went through there was never any doubt that he wouldn't finish it.
Great finish from El Kaabi - clinical.
Aston Villa 0-1 Olympiakos

Ayoub El Kaabi was onside and he didn't look it, but VAR has judged it and they have seen the lines and the goal is given!
Ayoub El Kaabi
It's given!
Disaster for Villa.
Chiquinho flicks the ball into the path of Ayoub El Kaabi who beats Robin Olsen.
It looked offside to the naked eye but Matty Cash was keeping him on.
Aston Villa 0-0 Olympiakos
Or is it? They're checking this.
Aston Villa 0-0 Olympiakos
It's Olympiakos' time to have a goal ruled out.
Ayoub El Kaabi is offside when he's played through by a nice flick so the fact his shot beats Robin Olsen is irrelevant.
Aston Villa 0-0 Olympiakos
Villa midfielder Douglas Luiz hits a low bouncing shot from distance and it's a simple stop for Konstantinos Tzolakis.
Aston Villa 0-0 Olympiakos
Aston Villa striker Ollie Watkins is holding his elbow. He seems to be in a bit of pain but he's playing on.
Marseille 0-1 Atalanta
Gianluca Scamacca, scourge of Liverpool in the last round of the Europa League, gives Atalanta the lead at Marseille.
The ex-West Ham striker hammers in a low shot which beats the keeper.
Aston Villa 0-0 Olympiakos
Villa push for a goal which would count but Leon Bailey's cross is headed away by David Carmo. Moments later the ball is back with keeper Robin Olsen.

Gesturing from the referee that there is a tug at the back-post.
Good refereeing.
Aston Villa 0-0 Olympiakos
Leon Bailey is celebrating but the flag is up.
Villa keep the pressure on from a corner and Ezri Konsa knocks the ball across the box, it hits an Olympiakos player and Bailey nods in from close range.
But Clement Lenglet fouled Vicente Iborra somewhere in the middle so it doesn't count.
Roma 0-0 Bayer Leverkusen
Not much action so far in the Italian capital. There's so much smoke from flares that it's a bit hard to see all of the pitch.
Aston Villa 0-0 Olympiakos

An outstanding save and it had to outstanding, full stretch finger tips from Konstantinos Tzolakis.
We thought Villa had scored!
Fiorentina 1-0 Club Bruges
A good start for Fiorentina's hopes of a second consecutive Europa Conference League final.
Riccardo Sottil has scored from distance to give the Italian side the lead.
Aston Villa 0-0 Olympiakos
So close from Villa's Morgan Rogers. He gets the ball from Douglas Luiz and tries to curl a shot into the bottom corner from 20 yards out but it's saved by a diving Konstantinos Tzolakis.
The resulting corner comes to nothing.
Aston Villa 0-0 Olympiakos

What a magnificent save from Robin Olsen!
What a ball from Daniel Podence, outside of the foot into Vicente Iborra and it was going to nestle into the top corner - Villa under-pressure.
Aston Villa 0-0 Olympiakos
Huge chance for Olympiakos and a brilliant save from Robin Olsen.
Daniel Podence puts in another fine cross and Vicente Iborra's header is looping towards the top corner but Olsen somehow claws it away.
Actually Iborra is offside, but Olsen didn't know that.
Aston Villa 0-0 Olympiakos
Ollie Watkins can't quite find Leon Bailey as Villa try to mount a first attack.
Aston Villa 0-0 Olympiakos
Wolves loanee Daniel Podence gets the ball on the left side for Olympiakos and tries to swing in a cross from deep towards Ayoub El Kaabi but Robin Olsen catches.
