Pep Guardiola will make a late decision on whether Sergio Aguero is fit to face Hoffenheim in the Champions League.
Manchester City take on the Bundesliga side on Tuesday having lost their first Group F game at home to Lyon.
Aguero, City's record goalscorer, has been carrying a foot problem but has travelled to Germany with the squad.
And Guardiola indicated he will give the Argentina attacker as much time as possible to prove his fitness.
"Tomorrow [Tuesday] is such a big game and Sergio is here because the doctors said he is able," Guardiola told a news conference.
