The victory in Cardiff's first Premier League home game will live long in the memory for the Bluebirds faithful, and Mackay heaped praise on Campbell.
The Scot believes performances of this quality mean Campbell could soon be adding to his solitary England cap.
Mackay said: "I thought Fraizer Campbell gave their whole back four problems today.
"He worked hard over the summer and I now think I have a player there who has had an England cap and, over the piece,
"I think could force his way back into that squad if he keeps his head down and keeps working and playing like that against top, top players."
