The Celtic boss, though, was as praiseworthy of Keane for his teamwork as much as his goals which took his tally to five since joining the Hoops in January.
"Top players have that motivation in-bred," Mowbray said.
"That's part and parcel of being a top player.
"For some of our younger players, hopefully it will rub off.
"They will see that, if you are going to play at the top level anywhere in the world - and Robbie has played all over the world - that is something which has got to come from within.
"It's not something you can switch on and off on match day.
"Another example would be Wayne Rooney. Whenever he plays, he runs around, tackles, chases and fights.
"That's driven from within, and I think Robbie wants to score goals, wants to help his team and his club.
"I was delighted with his performance on Sunday."
Mowbray warned his crocked stars not to expect to walk back into his team when fit again.
The Hoops boss was without Glenn Loovens, Jos Hooiveld, Thomas Rogne, Marc-Antoine Fortune, Diomansy Kamara, Niall McGinn and the suspended Scott Brown for the trip to Falkirk.
Next up is the Active Nation Scottish Cup quarter-final tie at Kilmarnock on Saturday lunchtime and the Celtic boss claims to have been given "food for thought"
by his fringe players at the weekend.
"The treatment room is full as you could see with the team we had out against Falkirk, but we will wait and see," Mowbray said.
"I'm not sure how they are coming along.
"They will have to get their boots on in training next week at some stage to be in contention for the weekend.
"But what the victory over Falkirk has given me is food for thought.
"The ones who didn't play will have to fight to get back in the team if the team continues to win.
"Players will have to compete for their places."
Mowbray declared himself especially pleased with 19-year-old Josh Thompson who fought out an intriguing battle against the powerful Enoch Showunmi.
"(Morten) Rasmussen played his part in Keane's first goal," he said.
"I thought (Marc) Crosas and (Landry) NGuemo were good in central midfield on a difficult surface and I thought Aiden (McGeady) played well.
"But Josh Thompson grows in stature every day.
"He was playing against a big, strong powerful boy with a lot of experience and if you put it in context, Josh is just a young boy who has played seven or eight games in his career.
"So he is doing okay."
