Olympiakos v Arsenal ratings: Yann M’Vila 4; Gabriel 7, Martin Odegaard 6, Willian 7

Gunners seal 3-1 victory against Greeks side in Europa League last-16 first leg

OLYMPIAKOS RATINGS: Jose Sa - 5: Showed incredible reflexes to push Aubameyang’s header onto the bar in the opening ten minutes. He denied the Gabonese striker again from a well struck free-kick from range, but he could and should have done better against Odegaard’s long-range effort. Could do little about Arsenal’s second and third goals. PA

Kenny Lala - 5: Had a tough night and couldn’t get close to Tierney in the first half. He managed to stop his forward runs after the break and even got forward himself as the game opened up. Reuters

Sokratis Papastathopoulos - 6: It’s no surprise that the defender who played 69 times for Arsenal gave everything against his old side. After a suspect opening 20 minutes, he managed to keep Aubameyang quiet. Getty

Oleg Reabciuk - 4: The full-back was guilty of giving away free-kicks in dangerous areas and he was replaced on the hour mark. Still finding his feet after January move. PA

Yann M’Vila - 4: Asked to play in the centre of defence and was booked for a wild challenge on Saka, which keeps him out of the second leg. He was out-jumped by Gabriel for Arsenal’s second goal. EPA

Mady Camara - 5: The defensive midfielder did his best to help the home side keep possession. He sprayed the ball around nicely when under no pressure, but could do little to stop Arsenal’s attacking midfielders. Getty

Andreas Bouchalakis - 5: Arsenal looked dangerous on the break and Olympiakos couldn’t handle it, Bouchelakis’ foul on Aubameyang the perfect example of how they gave away so many free-kicks. AP

Mathieu Valbuena - 4: Got away with a poor late tackle on Granit Xhaka on the 10-minute mark that summed up his evening. Looked like he’s lacking fitness. PA

Youssef El-Arabi - 7: The player who broke Arsenal hearts last season made them pay again when, after winning the ball back from Ceballos, he saw Leno off his line and slotted home from distance. He came close to a second, too. PA

Bruma - 6: The Portuguese winger was wasteful with the ball on the few occasions he had it in the Arsenal half. Constantly switched from left to right. He had the first chance on goal for Olympiacos. PA

Giorgos Masouras – 5: Had a glorious chance to equalise when he disposed David Luiz, but his shot was high and wide. Getty

SUBS: Kostas Fortounis - (On for Valbuena 46 : Has been in good form this season but he couldn’t influence this game. That said, Olympiacos looked better with him on the pitch. AFP

Jose Holebas - (On for Reabciu 59') 5: Was it a coincidence that soon after the introduction of Holebas, Olympiacos scored? Probably. The team looked vulnerable following his introduction. Lazar Randjelovic - (On for Bruma 59') 6: Came on and helped the home side keep hold of the ball more and also offered speed on the counter. Ahmed Hassan - (On for El Arabi 77') N/A. Thanasis Androutsos - (On for Masouras 86') N/A. Reuters

ARSENAL RATINGS: Bernd Leno - 6: Had quiet evening but when he was needed he was found wanting. He contributed to the Gunners losing possession for the equaliser and then couldn’t scramble back in time to make the save. PA

Hector Bellerín - 6: Solid at the back and looked decent going forward at times, making good runs that on one or two occasions were spotted by the likes of Odegaard. PA

David Luiz - 5: Classic Luiz: didn’t have much to do but put his side in trouble by losing possession in his own area. Luccky to get away with it. PA

Gabriel - 7: Magalhaes was solid in the centre of defence and he managed to get Arsenal’s noses in front with a marvellous leap and header. AFP

Kieran Tierney - 6: Just loves to attack and he was always looking to overlap Willian when possible. Got forward on several occasions and contributed to a promising offensive performance. EPA

Thomas Partey - 5: Didn’t quite make it through the hour but he had been solid if not unspectacular to that point. EPA

Granit Xhaka - 5 : Midfielder was under pressure following his performance at Burnley and though he was effective at putting the home side under pressure, he was still guilty of giving the ball away cheaply. Reuters

Bukayo Saka - 7: Was lively throughout and though he was unable to make his usual impact in the opposing area, he won enough free-kicks to give his team-mates some decent shooting opportunities. Getty

Martin Odegaard - 6: The Norwegian was having a sloppy game until he unleashed the opening goal of the game from distance. The power of his effort was too much for Sa in the home goal. Reuters

Willian - 7: Willlian’s improving form continued with a series of neat touches and clever link-up play from the left. It was from his cross that Gabriel scored Arsenal’s second. Getty

Pierre-Emerick Aubameyang - 6: He came close with a header early in the game, and again from a free-kick, but the Gabonese striker was kept quiet thereafter. AFP

SUBS: Dani Ceballos - (On for Partey 56') 5: Miss-timed his first pass when Aubameyang was through on goal and then gave the ball away for Olympiakos to equalise. Getty

Mohamed Elneny - (On for Willian 82') N/A: Made an immediate impact by grabbing Arsenal’s third goal with a fine strike from 25 yards. Getty

Emile Smith Rowe - (On for Odegaard 82') N/A: Gave the Gunners some fresh momentum going forward. Getty

Nicolas Pepe - (On for Saka 82') N/A. PA

Alexandre Lacazette - (On for Aubameyang 88') N/A: Didn’t have long on the pitch but still managed an effort on goal. Reuters

Martin Odegaard scored his first goal for Arsenal as Mikel Arteta's side secured a 3-1 win at Olympiakos in the first leg of their Europa League last-16 tie on Thursday.

Odegaard, who joined Arsenal on loan from Real Madrid in January, fired the visitors ahead with a 34th-minute strike from 25 metres before Youssef El Arabi equalised for the Greek team in the 58th minute.

Arsenal looked rattled after conceding a soft goal but Brazilian defender Gabriel restored their lead with a looping header and substitute Mohamed Elneny sealed the win with a long-range shot.

"We have to be very clear and honest with ourselves," manager Arteta said after the match. "We gave three chances to the opponent, they took one and at that level they are going to punish you.

"The goals and chances we have conceded are coming from ourselves.

"That's positive because when we stop it, we will be stronger. The reality is that we have to stop it immediately. It's my responsibility. I make them play the way we want to play it is just understanding the risk and reward."
