The Poland international has long been in the west London club's thoughts and interest could be revived as they look to sign a goalscorer
Chelsea's mission to sign a world class striker has seen them ask to be kept informed about Robert Lewandowski's situation at Bayern Munich.
Although Bayern are strongly opposed to a sale this summer, the 32-year-old could be tempted by a new opportunity overseas.
With just two years left on his contract at Allianz Arena, the Blues know their good connections with the Polish superstar could come in handy, having twice attempted to sign him in the past.
