Mikel Arteta's Arsenal maintained their 100 per cent record in this year's Champions League with a nervy 2-0 win against Olympiacos.

The hosts broke the deadlock midway through the first half when a sumptuous ball from Martin Odegaard split the Olympiacos backline, finding Viktor Gyokeres bursting through the centre of the park. The striker's effort bounced back off the woodwork, with Gabriel Martinelli on hand to turn home in front of an empty net.

After taking the lead though, Arsenal struggled to create opportunities and became increasingly under the kosh at the opposite end. The Gunners looked toothless in attack, until substitute Bukayo Saka danced his way through the defence and stuck one through the goalkeeper's legs.

David Raya - 8

The only Arsenal defender who looked switched on for the full 90 minutes. Pulled off a stunning save from close range in the opening half and was called upon on more than one occasion in the second.

Ben White - 6

Was caught on his heels for the chance Raya saved in the first half and continued to look leaky whenever Olympiacos came forward. Hooked on the hour mark and replaced by Jurrien Timber.
