Mesut Ozil's exile from the Arsenal first team continued on Thursday as Unai Emery left the midfielder out of the squad to face Vitoria.
The German playmaker has not featured for the Gunners since the 5-0 win over Nottingham Forest in the Carabao Cup last month.
On Wednesday, Ozil posted an image of himself laughing during a training session with a message which reads: "You make me laugh."
And before the Europa League clash against Vitoria kicked off, the 31-year-old took to Twitter to write another message.
He posted a picture of himself and former Arsenal midfielder Robert Pires with the caption: ‘Trained with this AFC legend this morning. Always a pleasure to see you my Bro @robertpires7. Best of luck for the match now from both of us.’
Speaking before the game, Unai Emery said: "We are improving defensively. We're receiving less goals. It's one objective we're doing.
"I don't want to achieve the best defensive solution with one system or using only those four players. In the Europa League we are using different players and they are also improving our defensive moments. It's for all the players.
"Above all I want to continue being, because we want to be, an offensive team, improving defensively but offensive. Our mentality is to be offensive. I am going to get that balance I am sure. Little by little.
"Now we are getting better as a competitive team, better defensively and we want also the next step to be to keep our capacity offensively. We are going to do that. After Monday we can be disappointed but it's only 24 hours."
