We continue to count down to Christmas with our own take on a traditional advent calendar, as we bring you a new player-based quiz to enjoy every day. Today's focus is on a long-serving Blues legend.
On every date between now and Christmas, we will bring you a quick quiz on a famous player or players who have worn that number on the back of their shirts for Chelsea. John Mikel Obi wore the number 12 shirt at Chelsea for over a decade during which time he won it all, but how much do you remember about the Nigerian's glittering career?
Just like with an advent calendar, you can come back and open a new quiz every day until Christmas Day. Unfortunately we can’t give you all a chocolate to enjoy with your quiz, but feel free to treat yourself if you score high. Good luck and merry quiz-mas!
