Manchester City manager Manuel Pellegrini has confirmed that striker Sergio Aguero will be sidelined for a month with a calf injury.
The Argentine international suffered the strain on Saturday during City's 6-3 win at home to Arsenal in the Premier League.
When asked how long Aguero would be out of action for, Pellegrini told reporters: "At least one month."
The forward has scored 19 goals in 20 games for City so far this season, including 13 in the league.
