Leeds United are working hard behind the scenes to bolster Marcelo Bielsa's squad for the new season.
With six weeks to go until 2021/22 campaign and a trip to Manchester United, the Whites are keen to strengthen several areas this summer.
Chief executive Angus Kinnear insisted the club's transfer activity is "well underway", with targets identified and talks ongoing to bring them to Elland Road.
Part of the fanfare behind a new addition is deliberating over what squad number they could receive and Leeds have several 1-11 shirts that are yet to be filled.
New recruits always have their ideal jersey numbers, so LeedsLive has taken a look at those vacant slots available this summer.
Number 3
With Douglas leaving the club, the first-choice left-back shirt is very much available.
Alioski currently holds number 10 and could switch if he extends his stay at Elland Road but otherwise, it seems a new signing will don three next year.
Number 8
Vurnon Anita was the last man to wear the number eight in 2017/18 and it's remained untouched since.
Kalvin Phillips and Mateusz Klich are the obvious names that could drop into the shirt but you'd have expected them to have done so already, if they were going to.
Stuart Dallas' new midfield role could perhaps lead to a change in number but otherwise, this ready-made for a new signing.
Number 10
It's not vacant yet but Alioski's uncertain future could open up the door for a number 10 at Elland Road.
There would be plenty of suitors, perhaps Klich would prefer 10 to eight? Raphinha seems a natural fit too, moving from number 18.
If not, it's the ideal shirt number for a big-name addition. A certain Matheu Cunha would certainly think so.
Number 12
A less fashionable slot as we move into the teens, last worn by Laurens de Bock.
Number 16
Yosuke Ideguchi was the last man to occupy this number in 18/19, which has been held by some journeyman before that such as Matt Grimes, Toumani Diagouraga, Nicky Ajose and Danny Pugh.
Number 19
Pablo Hernandez's imminent exit will leave the number 19 open for collection. Before the Spaniard, Lee Erwin and Steve Morison held the shirt.
Hernandez will certainly be a tough man to succeed.
Number 22
Jack Harrison has held this number for the last three years but he will return to Manchester City this summer.
A permanent deal is expected to be agreed, with his contract not expiring until 2023, but depending on when that is completed, he could be assigned a new number.
Number 26
Most recently donned by Liam Bridcutt in 17/18, 26 has been untouched ever since.
Number 27
Another unused jersey, Jamal Blackman's brief time as the last occupant was limited due to injuries.
Number 28
Gaetano Berardi has held this slot for over six years but it could have a new home next year.
Number 29
Jean-Kevin Augustin's ill-fated spell at Elland Road is the most memorable of those that have worn the shirt in the last 10 years.
Madger Gomes, Alfonso Pedraza and Casper Sloth came before him.
