The Black Cats have endured a woeful start to the Premier League season, picking up just one point from their opening six fixtures to leave them rooted to the foot of the table.
Their poor form has also seen Paolo Di Canio relieved of his managerial duties, despite him having signed 14 players over the summer.
Even without a permanent manager in place, the North East giants are already plotting their winter transfer plans in a bid to avoid relegation.
Musa has been earmarked as a potential addition thanks ti his fine form in Russia.
The 20-year-old has netted an impressive 17 goals in 50 outings for CSKA following his 2012 arrival from Dutch side VVV-Venlo.
The Moscow club are believed to value the youngster at around £10m, which has alerted Fenerbahce.
The Turkish giants are keen on the Nigerian, and could be a more desirable option than Sunderland.
Arsenal and Everton have also been linked with Musa, who has 31 senior international caps to his name despite his youthful age.
Should Sunderland take a few risks in January?
