Hat-trick hero against Everton last week, the Irish star didn't notch from a couple of chances in Saturday's win at Villa Park but was a constant thorn in Villa's side all afternoon.
In the end Teddy Sheringham volleyed home the winner in the second half and boss Glenn insisted the skipper benefited from the fact that Villa were always wary of his strike partner.
Glenn explained: "Robbie was always a threat and always stretching them.
"By doing that he gave Teddy a lot of space and Teddy was able to come off and link us together nicely.
"It wasn't a day for Robbie to get his finishing boots on but he made a massive contribution.
"It was touch and go sometimes for him, there were opportunities there that might have ended up in the back of the net but defenders can't rest against him.
"They can never go to sleep with him around and he's playing very well for us at the moment."
Glenn Hoddle has stressed that Robbie Keane doesn't always have to score to create havoc in opposing defences.
