Ferdinand singled out the four defenders, including John Stones who often drifted into midfield. He added: "I was sitting there thinking wow, the way that this team are defending - wow.
"I think that back four - [Manuel] Akanji and [Nathan] Ake one-v-one were exceptional, they nullified the threats wide that we highlighted before the game have been so dangerous. Dias, the amount of blocks he put in was phenomenal and Stones, defensively winning the ball, that was great as well.
"That there is the platform that builds everything else and decides what happens in other areas."
