Transfer deadline day always brings up some surprise sightings.
This year Italy legend Andrea Pirlo has assumed this particular role, sparking a massive response from a number of Arsenal supporters on social media in the process.
Of course, the former Juventus manager has a lot more free time on his hands at the moment after leaving the Serie A giants at the end of last season.
"My first season as a coach is over. It was a complicated and marvellous season at the same time," Pirlo wrote on Instagram following the announcement. "When Juventus called me, I never thought about the risks, even though they were pretty evident.
"The respect for this club prevailed and the same is true of my desire to play at the highest levels.
"If I could go back in time, I would make the same choice, despite all the obstacles I had to face, linked with a difficult situation for everybody which didn’t allow me to plan my choices and follow my playing style.
"However, I reached the required goals. This adventure ended in a way I didn’t expect but has made my future even clearer.
"I hope it will be full of the same satisfaction I’ve had as a footballer. It’s time to start again and face new challenges, I want to thank those of the Juventus family who supported me during the season."
And with extra time on his hands, Pirlo has chosen to spend deadline day in London.
Taking to Twitter and Instagram, the former midfielder uploaded an image of him crossing a road in the capital with a simple two-word message that reads: "London calling".
For some reason, some Arsenal fans have reacted to this post by calling for Pirlo to replace Mikel Arteta as manager.
