Andre Schurrle was included in the Chelsea travelling party following his recovery from a muscle injury that ruled him out of the weekend victory over Cardiff City.
Aside from Cole and long-term absentee Marco van Ginkel, Chelsea are sporting a clean bill of health for the trip to Germany, where they will be hoping to pull themselves level on points with Group E leaders Schalke, having bounced back from a matchday one defeat to Basel with a 4-0 win over Steaua Bucharest last time out.
Left-back Cole has made seven Premier League appearances for Jose Mourinho's men this season, as well as two in the Champions League.
