Atletico Madrid have opened talks with Chelsea over a January transfer move for Alvaro Morata, reports claim.
The Spain striker has struggled for form in a Blues shirt since signing for £60million from Real Madrid in 2017.
Sevilla signed Barcelona forward Munir El Haddadi last week, which ended their interest in Morata.
It has led to Atletico boss Diego Simeone moving to land the ex-Juventus hitman for the second half of the season.
Chelsea want the LaLiga giants to commit to an £8million loan fee with an obligation to permanently buy Morata at the end of the campaign.
Spanish outlet Marca reports Morata, who allegedly earns £8million-a-year, is willing to take a pay cut to rejoin the club he spent two years at as a teenager.
Atletico would need to offload players before finalising a deal with Gelson Martins and Nikola Kalinic being linked with moves away from the club.
Morata was a consistent goal scorer in Spain before joining Chelsea, scoring 20 goals for Real Madrid in the 2016/17 season.
His playing time has been restricted at Stamford Bridge by Eden Hazard and Olivier Giroud – and he will be even further down the pecking order if Chelsea, as they hope to do, land Gonzalo Higuain on loan this month.
