Chelsea had a bid of £31m turned down by Atletico last summer, but in light of their transfer ban being lifted, Abramovich is keen to make the best use of the January window and up their offer.
Aguero scored twice against Chelsea is the Champions League earlier this month, a performance which clearly impressed the club's manager Carlo Ancelotti.
The 21-year-old has a £53m buy-out clause in his contract, but Chelsea hope to get that price reduced.
