25-year old striker McKay took his season tally to 12 goals with a double in Caley's 2-0 win at Heart of Midlothian while 23-year old Watkins was impressive in the middle as Hughes' side remained second on the table with a 10th victory from 15 outings.
"Billy is an exceptional talent and a lovely kid to go and work with," he said.
"He certainly has that quality in his locker and showed that with a great right-foot and a left-foot finish.
"And Marley Watkins was different class. I have a soft spot for him because he is still a young kid and has been given the opportunity to come up here by Terry Butcher. He really gets himself involved.
"When he plays like he did today he is a real handful. He has all the tricks - stepovers, dragbacks. If I am looking to help him along, I would just say I'd like more goals out of him."
