Chelsea are one of four clubs in talks to sign Atletico Madrid midfielder Arda Turan, according to reports.
The 28-year-old has admitted that he could leave the La Liga side this summer, and revealed that his agent is in talks with "three or four" clubs.
The Daily Mail claims that the Blues are joined by Paris Saint-Germain, AC Milan and Barcelona in the race for his signature.
The Turkish international, who is expected to cost in the region of £25m, is thought to favour a move to the Premier League.
Turan joined Atletico from Galatasary in 2011.
