Chelsea are monitoring Monaco winger Aleksandr Golovin this season.
The Russia international has been a long-term target for Chelsea owner Roman Abramovich.
And Sport-Express says Abramovich could make a move for the midfielder at the end of this season.
Chelsea boss Frank Lampard has discussed adding greater creativity to his midfield and Golovin could fit the bill.
For the moment, there's a belief ASM would be prepared to sell the Abramovich favourite for €25-30m.
