The Spaniard has been absent for City's last three games due to an ankle injury, but is expected to return to the squad this weekend.
"The only player that we have injured is Jesus Navas," Pellegrini said in Friday's press conference. "All the other players in the squad are fit. David is a very important player for us so to be in the squad list is very important."
City are favourites to clinch the league title should they win their final three games of the season.
