Gambhir was involved in heated exchanges with Shane Watson and Simon Katich, but Gavaskar completely absolved the Indian opener and laid the blame squarely on the Australians.
"I don't think they (Australians) can stop and shove people from taking singles. I don't agree that all these are part of the game. They are not part of the game," he said.
"We need to make sure that these kind of things do not happen. These little things lead to bigger things," he added.
The Delhi batsman nudged Watson when he crossed him while completing the second run in the 51st over and then appeared to be ramming into Katich in the 78th over.
When asked whether Gambhir was to be blamed for the two incidents, Gavaskar said, "No, in the first instance you would see that Watson had stuck his hand out when he (Gambhir) was running and in the second instance when Gambhir was blocked by Katich inadvertently, I have to say, because he went to stop the ball."
"Then I think when he (Gambhir) wanted to take a single he got stopped. I think at that particular time words were exchanged and that can happen," he added.
The former India captain was at his sarcastic best when he said that the Australians will have to take Gambhir seriously as a batsman.
"I think it is a bit frustrating for the Australians. Gambhir was batting so well and they were not able to get him out. They don't rate him as a batsman. He has got two hundreds now and they have to admit he is better than what they think of," he told CNN-IBN.
