Pellegrini's men might have avoided such a big clash had they not misunderstood the group stage goal difference rules last week.
City beat Bayern Munich 3-2 but Pellegrini failed to realise that victory by one more goal would have secured top spot in their group and a theoretically more favourable draw.
Yet simply after beating the European champions, and then scoring six past Barclays Premier League leaders Arsenal, Pellegrini is confident enough after the draw.
He said: "I think they will be very concerned also. Barcelona is not the team it was two years ago. I think it is a beautiful game with two very good teams."u00a0
