Five changes for Chelsea from the West Brom defeat. Rüdiger and Christensen partner up in central defence. It will be interesting to see the extent to which the likes of Chilwell, James and Azpilicueta get forward from defence. Certainly plenty of options on the bench for Tuchel, should he require them.
