"It is going to be difficult but I think it will be very unprofessional of them if they didn't think that we were a threat," the midfielder said.
"For us, it is about staying focused and trying to repeat what we did last year."
Barcelona will once again be without left-back Jordi Alba due to a hamstring problem, while fellow defender Carles Puyol and playmaker Isaac Cuenca are recovering from knee surgery.
