Cape Town - Chelsea striker Diego Costa insists he is enjoying his football at Stamford Bridge, but also that he is feeling unsettled living in London.
The Spain international joined the Blues from Atletico Madrid in 2014 and has often been linked with moves away from Chelsea since arriving.
The 28-year-old has reiterated that he is enjoying his football at the club, but he has not adapted to life in London, which may further fuel speculation about his potential exit.
"I have two years of my contract left," he told SFR Sport.
"I am always very honest with the people around me. I always say that I am very happy at Chelsea.
"The club do a lot for me, the fans, my team-mates and this is a winning team, which motivates you to be there a long time more.
Costa, who netted 20 goals as the Blues claimed the 2014/15 Premier League title, was keen to return to his former club as Chelsea failed miserably in their title defence under Jose Mourinho.
