Arsenal continue to be linked with reinforcements in central midfield, and have less than three weeks until the summer transfer window shuts.
Lyon's Houssem Aouar is a name that has long been tipped to join Mikel Arteta's revolution and latest reports suggest a deal between the two clubs is making significant progress.
According to highly respected Italian journalist and transfer expert Fabrizio Romano, the 22-year-old wants to seal a move to Arsenal this summer - and this comes off the back of reports that a bid was being prepared.
If Aouar was to join the Gunners, supporters will be looking forward to seeing the Frenchman holding the Arsenal shirt at his unveiling - but what squad number could the playmaker take at the Emirates Stadium?
Since breaking into the first-team picture at Lyon, Aouar has worn numbers 8, 14, 16 and 25 on the back of his shirt.
At Arsenal, the incumbent no. 8, 14, 16 and 25 is Dani Ceballos, Pierre-Emerick Aubameyang, Rob Holding and Mohamed Elneny respectively.
And judging by the last two seasons and Aouar's history with the France U21's, his dream shirt number is '8' and it's unlikely he will get that at Arsenal given Ceballos has only recently rejoined the club.
However, the Spaniard is only on loan from Real Madrid and there's no guarantee he will sign on a permanent basis at the end of the campaign.
This means Aoaur could receive his favoured number if he's patient enough to wait a year or if Ceballos decides to relinquish his current shirt.
So, what other squad numbers will be available to the 22-year-old if he does sign for the Gunners at some point in the summer?
Below we take a look to see what numbers are currently free in north London.
No.13
David Ospina left the club after making the permanent switch to loan club Napoli last summer.
No.18
One of two shirt numbers Nacho Monreal had at the Emirates, but he departed for Real Sociedad last summer with the Gunners well-stocked for options at left-back in Sead Kolasinac and Kieran Tierney.
No.26
Emiliano Martinez's £20m move to Aston Villa means he has vacated the no.26 shirt.
No.27
With Konstantinos Mavropanos out on a season-long loan deal, his no.27 is currently vacant.
