Chelsea are reportedly desperate to sign Bayern Munich striker Robert Lewandowski before this summer's transfer window closes for business on August 9.
Bayern boss Nico Kovac recently dismissed suggestions that Lewandowski could leave the Allianz Arena this summer, although it is understood that the Poland international is still interested in a departure.
Real Madrid and Manchester United have been linked with the 29-year-old, who has scored 151 goals in 195 appearances for Bayern during his four seasons at the club.
However, according to the Daily Star, Chelsea boss Maurizio Sarri has identified Lewandowski as his number one transfer target this summer, and is determined to bring the forward to Stamford Bridge.
Chelsea, who have signed Jorginho and Rob Green this summer, will continue their preparations for the 2018-19 campaign with a pre-season friendly against Arsenal on Wednesday night.
