Lambert believes he brings an extra dimension to the Villa attack, which has been led by the 22 goals of Christian Benteke.
"Gabby has been playing ever so well. He is an absolute threat. He has speed and power, the speed to hurt teams," said Lambert, who recorded a second win at his former club this season to leave the Canaries with work still to do to ensure safety.
"If you have that in modern-day football, if you have that, it is a terrific weapon to have.
"Breaking Dwight Yorke's record is an outstanding achievement, he has been at the football club all of his career and has a great rapport with the crowd.
"He is playing really, really well at this moment in time.
"If he can keep doing that and we keep building, it will be great."
