Manchester City manager Pep Guardiola has said that he is yet to decide on whether Sergio Aguero will play against Celtic on Tuesday night.

Aguero has been handed a four-match ban by the Football Association after his second dismissal of the season for a wild lunge on Chelsea defender David Luiz.

City will now be without the Argentine until their trip to Liverpool on New Year's Eve, leading to the possibility of Aguero featuring in the Champions League meeting with Celtic despite qualification for the last 16 already assured.

The 45-year-old told reporters: "There will be changes tomorrow definitely. I'm so happy to be able to give minutes to people who deserve to play who perhaps didn't play the last game.

"That doesn't mean it won't be important to me. I will demand the best from those players. If Sergio is going to play or not, I will decide today or tomorrow. I don't know right know."

Aguero will be serving his second domestic suspension of the campaign, after previously missing three fixtures for his involvement in an off-the-ball incident with West Ham United defender Winston Reid in August.
