Pep Guardiola said that Erling Haaland and Joao Cancelo were both suffering from a fever against Dortmund in the Champions League.
The pair both started at Signal Iduna Park but, after a first half in which both had been well below their best, neither appeared for the second half as Bernardo Silva and Manu Akanji came on in their place.
Haaland did emerge at full-time to salute the Dortmund fans having spent two sensational years with the club. However, the City boss confirmed after the match that he and Cancelo had both been under the weather in the build-up to the game.
