Sergio Aguero has given Manchester City an injury scare ahead of the busy festive period.
The Argentina international was held out of Saturday's 3-1 win over Bournemouth with a muscle injury, and he is doubtful to face Watford and Chelsea this week after Pep Guardiola revealed club doctors warned him Aguero could be ruled out until January if he aggravated the problem.
"The doctors told me (on Friday) Sergio cannot play," Guardiola said. "If he plays, maybe it's four or five weeks off. In that situation, this month, with a lot of games, he was not safe."
City's all-time top scorer therefore seems unlikely to make the trip to Vicarage Road on Tuesday or Stamford Bridge on Saturday.
"Right now, I'm not quite sure," Guardiola said when asked about Aguero's availability. "We'll see. That's why I said before day by day we see. I speak with the doctors every day, they make a report and a briefing. They say 'ready' or 'not ready' and we decide."
Gabriel Jesus started against Bournemouth in Aguero's absence, but was unable to get on the scoresheet.
Though he scored a hat-trick against Shakhtar Donetsk last month, Jesus has scored only one league goal for City in a largely frustrating season to date.
