Chelsea have reportedly made a move to sign Bayer Leverkusen wonderkid Kai Havertz.
According to The Mail, the Blues have stolen a march on Manchester United, Real Madrid, Bayern Munich by opening talks for the £75 million-rated attacking midfielder.
To get fans excited about the 21-year-old's potential arrival, Bild are reporting that talks between Chelsea and Leverkusen are ongoing, and that the attacking midfielder can picture playing for the west London outfit.
Has he dreamed of what squad number he will ask for? Since breaking into the first-team picture at Leverkusen, Havertz has worn the no.29 shirt, while for the German national team he wore no.8 and no.20 this season.
But what shirt numbers will be available for the Germany international at Chelsea if Marina Granovskaia manages to pull off a stunning £75m deal?
Below, we take a look to see what numbers are currently free at Stamford Bridge.
No.6
The current owner of this shirt number technically is Danny Drinkwater who spent the first half of the season on loan at Burnley.
He returned to west London in January, although he was sent to Aston Villa in another loan deal.
No.10
Eden Hazard has now gone.
The player was out of contract at the end of the 2019/2020 season and since completed his move to Real Madrid following over a year of speculation regarding his future.
No.14
The No.14 is also currently up for grabs with Tiemoue Bakayoko spending the season on loan at AS Monaco.
No.15
Currently, vacant following Victor Moses' loan move to Fenerbahce at the start of 2019.
The Nigerian has since moved to Inter Milan for the remainder of the season and could earn a permanent contract with the Serie A giants should he impress.
No.16
No.16 could be a potential option for a new signing with Kenedy out on loan once again.
No.21
Davide Zappacosta's loan move to AS Roma has been disrupted by injury, but his squad number at the Bridge is currently vacant.
No.25
Although the No.25 shirt has not been officially retired by the club, it seems that Chelsea do not want anyone to take on Gianfranco Zola's famous number.
Departing for his home country back in 2003, nobody at the club has worn the shirt since the Italian maestro departed 16 years ago.
No.26
As is the case with the No.25 shirt, John Terry's No.26 may well be left vacant following his trophy-laden spell at Stamford Bridge.
No.27
Andreas Christensen's move to the no.4 has left the no.27 vacant.
No.30
This became vacant when David Luiz joined Arsenal in the summer.
It's a squad number that has been worn by the likes of Yossi Benayoun, Tiago and Jesper Gronjkaer in the past.
No.32
The No.32 shirt has been vacant following Marco Amelia's departure in 2016.
Andreas Christensen, the club's current No.4, had worn the number during the 2012/13 season.
