Pep Guardiola's side responded to defeat against Lyon in their opening game with a late victory in Hoffenheim last time out, and will hope to continue their winning streak as they take on Paulo Fonseca's Shakhtar.
David Silva, Fernandinho and the Premier League leaders trained in the Ukrainian rain ahead of the game in Kharkiv, though will be used to such conditions in the Premier League.
Kevin De Bruyne - recently having returned from a knee injury - and Bernardo Silva seemed to be enjoying themselves in the training session.
The Portuguese also spoke ahead of the fixture, remarking: "Usually after an international break, most teams lose a little bit of the way they play but we were really focused and hungry for more titles and more wins.
"The team has had a fantastic start and are top of the league and in the Champions League we want to beat Shakhtar and go top of the group.
"And we are through in the Carabao Cup, so it's been a great start. We need to keep it this way."
