Arsenal v Olympiacos Piraeus - as it happened

FT: Arsenal 0-1 (10) Olympiakos!! (agg 3-2)!! All over at the Emirates and the Gunners were fairly comfortable. Each team just had one chance each in the first half, the Greeks started the second 45 well and El-Arabi gave Olympiakos hope, but they couldn't build on that. Ba stupidly got himself sent off towards the end and that showed Olympiakos' frustration. Arsenal worthy winners over the two legs.

Arsenal have a corner here.

Tierney is booked for taking too long to take the throw in.

Three added minutes.

Olympiakos cross the ball into the box and it comes to nothing.

Save by Sa to deny Auba from Martinelli's pass and then Auba's acrobatic effort on the rebound goes over!

Xhaka is booked for a late challenge.

Olympiakos double sub:

Olympiakos red for two quick yellows! Ba knocks over Martinelli with his arm, he's booked and he then bats the ball away in frustration at the ref and is sent off for two yellows! Stupid.

Arsenal double sub: Martinelli for Smith Rowe and Chambers for Bellerin.

Auba!!! What have you done?? Olympiakos send players forward, Arsenal counter through Auba, he runs and is one on one with Sa and his finish is shocking.

Auba gives away a free-kick now.

Pepe goes forward again, but hits a weak effort at Sa.

The ball goes straight into the wall.

Camara is brought down by Thomas just outside the area and this is dangerous.

Olymiakos sub: Androutsos is replaced by Bruma and Randjelovic is on for Masouras.

What a chance for Pepe!! Tierney crosses low for Pepe in the middle of the area and Pepe's goalbound strike hits Smith-Rowe on the back and that sends the ball over the bar!

Still 0-1 here and the goal seems to have woken the Gunners up.

Olympiakos again!!! Holebas flicks on the corner with his head and a teammate so nearly gets on the end of it at the back stick!

Second half underway here at the Emirates!

HT: Arsenal 0-0 Olympiakos (agg 3-1)!! Half-time at the Emirates and the hosts are very comfortable. There have been very few chances. Pepe had a clear opportunity for the Gunners while El-Arabi forced a fine save out off Leno, but otherwise, there has been little to report. I can't see the Greeks getting three in the second period. Back shortly!

45+2: Smith-Rowe!! Arsenal take a quick free-kick, Ceballos runs towards the box and then lays off to Smith-Rowe and his shot towards goal is easily caught by Sa.

45+1: Reabciuk is knocked over by Pepe and the Greeks get a free-kick.

Two extra minutes.

Free-kick to Olympiakos 25 yards from goal after Pepe catches Androutsos. Pepe looks bemused by the call and there doesn't look much in that.

Both players should be able to carry on although Sokratis seems to have come off worse. Smith-Rowe has a bit of claret around the nose.

Smith-Rowe has got injured by the ball and Sokratis by Smith-Rowe's follow through into his leg.

Nasty collision here!!! Elneny gets the ball, he passes to Smith-Rowe, he shoots from outside the box, the ball hits the defender on the leg and then the ball smacks Smith-Rowe in the face!

Olympiakos get us going from right to left in the blue while Arsenal are in red and white!
