Mourinho used statistics to say "records" had been broken in three consecutive matches, despite saying such figures meant "very little" to him as recently as Friday.
"We run and we run and we work more than ever and at certain intensity that we never did before," added Mourinho, who says he is working individually with his strikers.
"Our levels of ball possession are much higher than before too. Our chances are higher than ever.
"Our number of goals is lower than ever. You have the numbers, you read the numbers, you get some conclusions.
"For me they mean something. It means it's everybody's responsibility."
