However, Moyes feels that his players are ready for the challenge that Manuel Pellegrini's side will provide on Tuesday.
"We go in [to the derby] after a better showing and, if we play as well as we did at West Ham, then we'll make opportunities and, if we play with the same heartbeat we showed against Olympiacos, then we'll be very hard to play against and have a big spirit in the game," Moyes told The Guardian.
"Hopefully we're starting to pick up and play better. We're certainly going into our next game confident and ready to get a result."
United are seventh in the table, while City sit third.
