Bayern Munich continued their relentless march at the top of the Bundesliga with a thumping victory over Hoffenheim.
The German Champions prepared for their trip to the Etihad Stadium with a 4-0 victory to go seven points clear at the top.
Mario Gotze, Robert Lewandowski, Arjen Robben and Sebastian Rode were all on the scoresheet, and Bayern remain undefeated in three competitions so far this term.
Pep Guardiola’s men welcomed back Bastian Schweinsteiger after injury, who emerged from the bench to set up the fourth goal for Rode, himself a second half substitute.
However, Guardiola felt the scoreline flattered his side, who he said did not retain possession well enough.
The former Barcelona boss said: "We had problems with our build-up play in the first 15 minutes and we carelessly gave the ball away too often.
"I think 4-0 is too big a win. The result doesn’t reflect what happened on the pitch. But I’m very pleased after the international break. It's three more points to us."
Bayern have already qualified as group winners from Champions League Group E with maximum points from their first four games.
City still have a chance of progression to the knockout rounds, and will complete their group stage fixtures with a trip to Rome next month.
The Italian side face CSKA Moscow on Tuesday night, and will go into that encounter on a winning note after coming back to see off Atalanta 2-1 in Serie A on Saturday.
Maximiliano Moralez gave the hosts an early lead, but Adem Ljajic levelled on 23 minutes and Radja Nainggolan found the winner before half time for Rudi Garcia’s men.
Ljajic was in top form for the team from the Italian capital, cutting inside before producing a beautiful finish for his side’s opener and setting up Nainggolan for the winner.
Garcia said: "I've been saying Ljajic is a talented player for 18 months. I'm lucky to be able to give all my forwards game time.
"Ljajic played really well tonight. He took his goal superbly then set up Nainggolan for the other."
Roma retain second place in the league, three points behind pace-setters Juventus.
Meanwhile, CSKA Moscow fell to a third straight league defeat at the hands of Krasnodar.
Two goals from Brazilian Ari within the first six minutes were enough to condemn Leonid Slutsky’s side to an away loss, despite Roman Eremenko’s 14th minute strike.
CSKA lie third in the Russian Premier League, 10 points off leaders Zenit.
