Mari starts, Kolasinac returns: 4-3-3 Predicted team vs Olympiacos

Arsenal will be hoping to take an early advantage in the Europa League round of 32 tie when they face Olympiacos on Thursday evening.
While Hector Bellerin, Bernd Leno and David Luiz have to keep their spots in the back five – because they have not put a foot wrong – a couple of changes might be necessary
First of all, with Pablo Mari being declared fit for selection (as per Arsenal.com), the Spaniard deserves to finally make his bow and it would be interesting to see a left-footed defender paired up with Luiz.
At left-back, the fact that Bukayo Saka has had fitness issues in recent weeks means it is about time he got a rest and that is why Sead Kolasinac should make his return to the starting eleven.
In midfield, the trio should be Granit Xhaka, Dani Ceballos – who was delightful to watch on Sunday – and Matteo Guendouzi – who should play despite the off-pitch controversies since Lucas Torreira is not available.
The attacking trio should include Pierre Emerick-Aubameyang and Nicolas Pepe who were impressive on Sunday while Eddie Nketiah makes way for the prolific Gabriel Martinelli.
PREDICTED TEAM

Bellerin – Luiz – Mari – Kolasinac
