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.

After starting yesterday with Petr Cech, door number two on our advent calendar contains a mix of right-backs and centre-backs in the form of a trio of Chelsea's European trophy winners. Petrescu helped us lift continental silverware for the first time in over a quarter of a century, when we claimed the 1998 Cup Winners' Cup and the same year's UEFA Super Cup, while Ivanovic helped win the Champions League and Europa League for the first-ever time in 2012 and 2013 respectively. Of course, Rudiger has claimed three European winner's medals with the Blues, following the 2019 Europa League with the Champions League and Super Cup this year.

Try the quiz below and find out how well you know our trio of number twos. 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!
