Manchester City are without star striker Erling Haaland for tonight's Champions League trip to Crvena zvezda.
The match in Serbia is a dead-rubber for both teams, who will finish top and bottom of Group G respectively regardless of the result.
Therefore, changes have been made by City ahead of their match against Crystal Palace on the weekend and subsequent Club World Cup campaign.
Haalandhas been left at home having picked up a stress-related foot injury before the game at Luton.
"He will be back on Thursday, day after tomorrow, and we see how he feels," Guardiola told a press conference.
"I cannot answer [if he will play on Saturday], I don't know right now. The next press conference I can be more precise about his condition."
Jeremy Doku is also absent for City, who remain without the long-term injured Kevin De Bruyne.
"It’s muscular," Guardiola said of winger Doku. "It's not a big, big issue like Kevin was for example.
"We have to think about it as well because he of his explosiveness. We have to be careful. I don’t know when he be ready, maybe one week or two weeks he will be ready again."
There is a rare start for Kalvin Phillips in midfield, while Stefan Ortega Morena starts in goal and youngsters Micah Hamilton and Oscar Bobb get their chance to impress.
