Tottenham Hotspur look to be gearing up for a busy January transfer window.
Despite bolstering his first-team squad in the summer with several shrewd additions, Spurs boss Jose Mourinho is being tipped to do more business in the new year.
The latest name being linked with a move to the Tottenham Hotspur Stadium is that of RB Leipzig attacking midfielder Marcel Sabitzer.
According to reports in Germany, Mourinho is interested in signing the Austria international, who in turn is reportedly keen on the idea of joining the north London outfit at some point in the future.
If Sabitzer was to join the Lilywhites, supporters will be looking forward to seeing the 26-year-old holding the Tottenham shirt at his unveiling - but what squad number could the midfielder take in N17?
Well, it would appear that Sabitzer has two favoured options.
He's worn no.7 for RB Leipzig ever since joining from Red Bull Salzburg five years, but for the national team he has worn no.9 since upgrading from no.20 in the 2016/17 international window.
At Tottenham, the incumbent no.7 and no.9 are Son Heung-min and Gareth Bale respectively.
Unless Son is willing to vacate his shirt number, then Sabitzer would have to look elsewhere if he was to become the South Korea international's teammate next month.
Although, the no.9 shirt could be available at the end of the season as Bale is only on loan from Real Madrid and his long-term future hasn't yet been sorted.
With that said, what other squad numbers would be available to the midfielder if he does sign for Spurs in the January transfer window?
Below, we take a look to see what numbers are currently free at Tottenham.
No.13
Usually reserved for the second-choice goalkeeper in the squad, the number 13 was made vacant this summer following Michel Vorm's exit.
No.16
With Kyle Walker-Peters having joined Southampton, the number 16 is available for any new Spurs signings.
No.26
Although the No.26 shirt has not been officially retired by the club, it seems that Spurs do not want anyone to take on Ledley King's famous number.
Nobody at the club has worn the shirt since the defender retired in 2012.
With Ryan Sessegnon, Juan Foyth, and Oliver Skipp all out on loan this season, technically no.19, no.21, and no.29 are all vacant at the moment.
