I was never friends with Irrfan but there's no rivalry: Nawazuddin

Actor Nawazuddin Siddiqui says that there is no rivalry between him and his The Lunchbox co-star Irrfan Khan. "We were never friends earlier also and not now as well. We work together whenever we are cast in a film together. In the future if I get to work with him I will surely do it," he says.
