ArsenalOlympiacos

Arsenal is in great form at home: they've won all three competitive home matches this season with a total goal difference of 9-2, and have won the previous 13 European home games as well. The defense is solid - David Raya has conceded only 3 goals in 7 matches, and the expected goals against (xGA) is also low (0.43 per match).

Olympiakos is struggling away in international play: they've lost the last 10 away group stage matches in the Champions League, and this season's only European clash where they didn't score was a 0-0 against Pafos (0.3 xG). Their most dangerous finisher, El Kaabi, gets few balls away (an average of 4 progressive passes/game), thus he's expected to have few chances.

• Arsenal scores an average of 2.3 goals per match, while Olympiakos' opponents score an average of 0.60 goals against them.
• Saliba returns for Arteta's team, but the visitors can't include the creative Cabella and Yazici in the Champions League squad - this further weakens the Greek attack.
