The Coronavirus pandemic has hit Russian clubs hard and 13-time champions CSKA need to generate revenue from sales.
22-year-old forward Chalov is a candidate to be sold and that news has alerted German sides.
According to FT, CSKA were demanding €20m for the twice-capped Russian international after his strong pre-season.
But in light of the current situation, the club would now accept half of that plus bonuses.
An appealing profile
All three German clubs could find themsleves in need of a player with Chalov’s profile this summer.
Lucas Alario’s future at Bayer Leverkusen is uncertain as he wants more playing time after often being used as a sub.
Meanwhile, Hoffenheim could sell either or both Ishak Belfodil and Andrej Kramaric.
Belfodil fell out with management late last year and hasn’t played since September having undergone knee surgery.
And Wolfsburg will have to fight to keep star striker Wout Weghorst, scorer of 20 goals this season.
Volkswagen-owned Wolfsburg have been losing money and might not be able to resist a good offer for Weghorst.
