Porto defender Bruno Alves is being linked with a move to Chelsea.
The 27-year old Portuguese international says leaving his current club is an option and it is believed the Blues are ahead of Italian club Inter Milan to acquire his services.
"Leaving Porto is an option to me, but a deal is yet to be done," Alves told SIC during the Portuguese league awards.
"As a consequence I am fully concentrated on the Portuguese Cup final in order to claim the double this year."
