During December there have been quick quizzes on a famous player or players who have worn that number on the back of their shirts for Chelsea.
Today you have questions on Blues legend Gianfranco Zola to get your teeth into on Christmas Day.
Just like with an advent calendar, you could come back and open a new quiz every day until today. 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!
