The Israel international’s contract is due to expire at the end of the year, meaning he is free to negotiate a Bosman transfer with interested clubs.
Izvestia has revealed that Stuttgart are hoping to sign the player on a free transfer in January, just like several Russia’s top clubs.
However, Natkho does not appear to be keen on leaving Kazan and he is currently negotiating a contract extension with his employers.
Bibras Natkho joined Rubin in a low-profile move from Hapoel Tel Aviv in the winter of 2010, but he quickly established himself as a first team regular.
The 25-year-old went on to make no less than 92 Russian Premier League appearances, scoring 20 goals in the process.
He remains a key player for both club and country and has so far scored 4 goals in 28 Israel caps.
