What is yet to be established is when you put the access code into the website to buy the ticket whether this brings up the name of the seasoncard holder and you have to buy in that name, or it is not person specific and the ticket can then be purchased in any name you want.
This is hugely significant and will answer a lot of questions that are getting put on this thread.
If it has to be purchased in the name of the seasoncard holder, UEFA do allow the transfer of tickets from one person to another for this game. It remains to be seen whether this is just tickets from the general population or if it includes the tickets allocated to City and Inter.
