Besiktas claim to have agreed fee for Chelsea's Demba Ba
Orman has revealed that Chelsea were valuing unwanted Ba at £10million, but that Besiktas have negotiated the price down.
“Demba Ba is an excellent player and we have been in talks with Chelsea for a long time over bringing him to Istanbul,” said Orman. “Talks are ongoing, Chelsea initially wanted £10 m for Ba, but we have negotiated a price we are happy with. We'll tell the media once the final deal is done.”
Spain forward Costa has long been linked with a switch to Stamford Bridge and the clubs agreed a fee early this month, with Chelsea meeting his buy-out clause reported to be worth £32million.
A Chelsea statement said: "Chelsea is delighted to announce Diego Costa has completed his transfer from Atletico Madrid by signing a five-year contract. He will join up with the first team for our pre-season European training camp next week."
Costa said: "I am very happy to sign for Chelsea. Everybody knows it is a big club in a very competitive league, and I am very excited to get started in England with a fantastic coach and team-mates.
"Having played against Chelsea last season I know the high quality of the squad I am joining. I would like to thank everybody at Atletico who made me into the player I am, it was an incredible time for me, but now I am starting a new adventure and I hope to win many trophies with Chelsea."
Meanwhile, left-back Patrick van Aanholt, who has spent the past three seasons on loan at Vitesse Arnhem, claims he will be leaving Chelsea this summer. “Where will I play next year? I don’t know, but not Chelsea. I’m done here,” he said.
