The 27-year-old has joined the Blues on a five-year deal. And he took no time to post a picture of himself in a Chelsea kit on his official Facebook page (see above).
Said Fabregas, per Chelsea's official statement:
I considered all the other offers very carefully and I firmly believe that Chelsea is the best choice. They match my footballing ambitions with their hunger and desire to win trophies. They have an amazing squad of players and an incredible manager. I am fully committed to this team and I can't wait to start playing.
