Chelsea boss Jose Mourinho is backing both Manchester clubs to make progress in their Champions League ties.
Mourinho says both Manchester City and Manchester United can overturn their first leg defeats in Europe.
"They lost at home, but can't Manchester City win in Barcelona?" said the Chelsea manager. "No? Barcelona lost to Valladolid and lost at home to Valencia. Why can't they win? Why can't Man United change that result against Olympiakos? I think they can. I think they're going through. Arsenal at Bayern, can they win 2-0 and go to extra time? Difficult, probably the most difficult of the three but they can."
