In six games together, the pair have contributed nine goals to six wins, with another three at Old Trafford helping United account for Middlesbrough in a 4-1 win which saw the hosts equal a 100-year-old record.
Not since Billy Meredith's day have the Red Devils scored four times in four successive games and while that record is not likely to be extended in next Saturday's crunch showdown with Arsenal at the Emirates Stadium, it is the Gunners who should be fearful as Rooney and Tevez scent blood.
"They will mature and develop as experienced players. When they do that, hopefully we will see the complete partnership."
Ferguson claimed United's third goal - and Tevez's first - summed up the effectiveness of their partnership.
After cushioning Anderson's lofted pass into Rooney's path, Tevez continued his run, finishing clinically when the Merseysider returned possession with an inspired back-heel.
"It needed quick thinking, great vision and courage," said Ferguson.
"Wayne was in the box and he could have taken a touch. But he knows Carlos is making the run and the back-heel puts him in. It was a fantastic goal."
The sublime effort effectively sealed victory for United, although it had a major rival for goal of the game given Nani had put the hosts in front with an unstoppable 30-yard piledriver even better than the memorable winner against Tottenham two months ago.
"Nani only deals in thunderbolts," enthused Ferguson.
"He is coming along nicely for us now and he had a great impact today."
And the news from Stamford Bridge after the final whistle only brought even more glee as rivals City had been thumped 6-0 by Chelsea.
"For weeks we were only scoring one, now it is four," said Ferguson.
"Some of our attacking play at times is very good."
