Pierre-Emerick Aubameyang was unable to travel to the Etihad Stadium for the FA Cup third round defeat to Manchester City due to a back issue, Graham Potter revealed following the game. The Chelsea boss noted the former Arsenal striker had a 'tight back' on Saturday.
The forward was present off the bench in the Premier League clash against Pep Guardiola's side after he replaced Raheem Sterling, but looked disgruntled when substituted after an hour on the pitch at Stamford Bridge. Sterling remains out with a hamstring issue suffered in the fixture.
Christian Pulisic, also injured in the Premier League clash against Manchester City, looks set to be out for weeks, however. The American international damaged his knee in Chelsea's home clash before being replaced by Carney Chukwuemeka.
