Pellegrini's men, with a two-point advantage over Liverpool and much superior goal difference, effectively now need just a point from their final game at home to West Ham on Sunday to finish the job.
But Pellegrini said: "We beat them here in the Capital One Cup, it was a very good game and I hope we can repeat it tomorrow, but the best way to do it is to play in the same way.
"We did it especially against Aston Villa. I think that was one of the best games we played the whole year."
