What shirt number could Kai Havertz wear when he joins Chelsea in a big money move from Bayer Leverkusen with the Blues willing to pay the €80m (£73m) asking price?
The Bayer Leverkusen playmaker has donned the number 29 shirt for the past four seasons at Leverkusen but wore the number 17 for their under-19s side and the number 10 for the under-17s.
He has also worn the numbers 7, 20 and 23 for the German national team.
Currently, Havertz's favoured number 29 is in the possession of defender Fikayo Tomori but it does not seem the England international has any particular affiliation with the number and may be willing to let Havertz take it.
The number 10 shirt could also be up for grabs with current wearer Willian expected to leave the club when his contract expires at the end of the season.
But what shirt number will he wear?
Of the other numbers Havertz has worn throughout his career, 17, 7 and 20 are currently taken by players unlikely to leave in the near future in Mateo Kovacic, N'Golo Kante and Callum Hudson-Odoi.
The number 23 is expected to be available, though, with Michy Batshuayi's time at the club seemingly up with Werner, Tammy Abraham and Olivier Giroud in the pecking order.
Other numbers which could be given to Havertz include the 6 shirt, number 14, 15, 16 and 21.

14, 15, 16 and 21 are all vacant with the most recent wearers, Tiemoue Bakayoko, Victor Moses, Kenedy and Davide Zappacosta, currently out on loan and likely to leave permanently this summer.
