There were some good Arsenal moments during the first half of their Europa League encounter with Eintracht Frankfurt at the Emirates.
But it was something that happened off the pitch that caught the eye.
The Gunners created a number of good openings to take the lead against the Bundesliga side, with Gabriel Martinelli having a couple and Pierre-Emerick Aubameyang and Bukayo Saka having one each.
They looked up for the game and were chasing down everything, hassling and harrying the Germans in possession in what looked to be a show of solidarity behind their under-fire head coach.
And while Emery has been having plenty of problems because of the results his team have been suffering on the pitch, he had a bit of a problem with his clothing during the first half.
Predecessor Arsene Wenger was often derided for the long overcoat he wore on the sidelines, with the Frenchman being caught on camera more than once struggling to undo the zip all the way down.
And Emery' issue came with his jacket too, although it was brought on by a UEFA official.
Emery was forced to change on the sidelines because his black jacket clashed with the black shirts worn by visiting side Frankfurt!
The Arsenal head coach could not believe it and a member of his backroom staff had to go back to the changing room to get the head coach a grey one instead.
