Mourinho was delighted with the pair after victory over Leicester City.
"The best game of Paul Pogba? I do not know. He has not played badly against Southampton. He has not played badly against Hull City. When the team is not playing well, he does not play very well. When the team is better, he's better.
"More is expected of him and the team. They should be more regular in the image of the whole team. Pogba and Herrera had a good match, they are complementary."
