Besiktas are reportedly pressing ahead with their bid to land Chelsea striker Samuel Eto'o this summer.
The 33-year-old, who joined the Blues from Russian club Anzhi Makhachkala last August, is expected to leave Stamford Bridge at the end of the season.
Besiktas have now sent delegates to London to open talks with the Cameroon international, according to the Daily Mail.
Should Eto'o join the Black Eagles, it is said that he will receive around £6.5m a year in wages.
The same report suggests that Besiktas manager Slaven Bilic is also interested in signing Lyon striker Bafetimbi Gomis, who is also available on a free contract at the end of the current campaign.
