That’s according to beIN Sport reporter Tancredi Palmeri.
Spanish journalist Manu Sainz claimed last night that the Premier League champions were interested in the City hitman.
Chelsea are on the lookout for a new striker after Antonio Conte told Diego Costa he was surplus to requirements.
And after missing out on Romelu Lukaku to Manchester United the Blues have widened their search.
Palmeri says Chelsea are acting on their interest.
He tweeted: “BOOM! Chelsea in talks for Aguero!”
Aguero has fallen down the pecking order at The Etihad since the arrival of Gabriel Jesus.
Jesus has been Pep Guardiola’s first choice since arriving in January.
Aguero fired 20 goals last term while Jesus scored seven in 10 appearances. Injury ruined his season but the 20-year-old is expected to be the main man next term.
Sainz yesterday claimed Guardiola had given the thumbs up for Ageuro to head to west London.
