New signing Granit Xhaka will now wear the No 29 shirt next season.
The number has special significance for him as it is the reverse of his year of birth - 92.
We had previously announced he would be wearing No 16. Supporters who ordered shirts with his name and the original number via Arsenal Direct or in Arsenal stores will have their shirts automatically printed with the new number.
We apologise for any inconvenience this causes but hope our supporters understand the special circumstances on this occasion.
