Chelsea have joined the race to sign Arsenal skipper Pierre-Emerick Aubameyang, according to a report.
The Gabon international has yet to agree a new deal with the Gunners and is due to become a free agent at the end of next season.
Manchester United, Real Madrid and Barcelona are believed to be among the clubs monitoring Aubameyang's situation ahead of the next transfer window.
Bleacher Report claims that Chelsea are also tempted to make a formal approach for the 30-year-old, who has scored 49 goals for London rivals Arsenal in 75 Premier League appearances.
Blues boss Frank Lampard is said to be after a new striker and Aubameyang fits the bill as a prolific striker who knows English football well.
Former Arsenal striker Charlie Nicholas has urged the club to demand £100m for the ex-Borussia Dortmund star if he does not agree a new deal before the summer.
