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.

Today you have questions on two number 24s to test your knowledge, with current holder of that shirt number, Reece James, as well as former Blues centre-back Gary Cahill in today's quiz.

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!
