Manchester City's game against Leicester will be too soon for captain Vincent Kompany's comeback but the centre-back is close to a return after a lengthy spell on the sidelines with a calf injury.
"Kompany and (Eliaquim) Mangala both started working partially with the squad - unfortunately Mangala has another injury and he'll be another couple of weeks," says Pellegrini.
"I hope after another week, Vincent will be back working with the squad fully.
"We know exactly what happened with the injury to Vincent now. The risk for the future is exactly the same as it is with every player. It's important now for Vincent to start playing again as we have just 14 senior players. That's not so many for so many games."
