Pablo Mari was left out of Arsenal's squad for the 1-0 win over Olympiacos on Thursday night, but the centre-back still managed to make a memorable impression.
The Spanish defender, who joined the Gunners on loan in the January transfer window from Flamengo, stood up to complete his initiation song in front of his teammates; choosing Ricky Martin's hit single 'Maria'.
Mari's performance was captured by Arsenal captain Pierre-Emerick Aubameyang, who shared the video to his Instagram story after the match.
The centre-back is seen singing and dancing in the routine, much to the amusement of the Arsenal squad who can be heard clapping and laughing.
The defender had been expected to be included in the squad for the clash against Olympiacos after playing 45 minutes for the Under-23 side in a 2-1 defeat to Chelsea on Monday.
But Arsenal head coach Mikel Arteta appears to be slowly integrating the defender, with Sunday's clash against Everton another potential opportunity for his full debut.
Speaking before the Europa League clash in Athens, Arteta had expressed his delight that Mari was bedding in well since his move from Flamengo.
"When he joined the club he hadn’t played for a long time and he had a little niggle as well when he joined us, but his attitude and commitment has been really, really good and highly surprising," said the former Man City coach.
"He did really well the other day and hopefully we can start to use him soon."
The Gunners took home a one-goal advantage from the first leg of their last-32 Europa League tie, thanks to a late Alexandre Lacazette goal.
"It’s tough to come to a stadium like this away in Europe and come away with a win," Arteta told reporters after the game.
"There are a few lessons within that game for us, and some great things for our development as well as a team. The first 10, 15 minutes we suffered because we did not do the things that we talked about and the execution on the simple things was poor.
"We had the situations to break them and run after them and we kept giving simple balls away. In many moments it did not allow us to have the continuity to travel with the ball and play in the opposition half more."
