We are counting down to Christmas with our own take on a traditional advent calendar, with a new quiz every day, and with only a few left to go the focus turns to a famous number 23.
On every date between the start of December and Christmas, we have been bringing you a quick quiz on a famous player or players who have worn that number on the back of their shirts for Chelsea.
With only two days left until Christmas Day, it is the turn of former Blues goalkeeper and current loan technical coach and club ambassador Carlo Cudicini. It is his time as a player we are looking at here, as we bring you five questions on a career which included a decade at Stamford Bridge and several trophies.
Try our quiz and find out how well you know the Italian. 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!
