Jose Mourinho’s men are gearing up for the group-stage encounter on the back of Saturday’s 2-0 victory over West Bromwich Albion at Stamford Bridge.
The west London side played Schalke in last season’s group stage, with Chelsea winning 3-0 in Germany and at home.
The sides also faced off in the 2007-08 group stage, with Chelsea 2-0 victors in London, Didier Drogba scoring the second, before a goalless draw in Germany.
Roberto Di Matteo, the manager who led Chelsea to their 2012 Champions League triumph, now stands in the way of the London side’s attempt to secure their place as Group G winners.
Schalke appointed Di Matteo as coach on 7 October following the departure of Jens Keller. It is the Italian’s first role since leaving Chelsea in November 2012.
Here are some of the best pictures from Monday morning’s training session at Cobham.
