Former India captain Sunil Gavaskar disapproved of Virat Kohli swearing at the Australians after scoring a century, terming it 'schoolkid' temperament.

Kohli had a wild celebration after reaching his century with some choicest of words against the Australian players, and Gavaskar said it was unnecessary.

"Not just Virat, some other Indian players also. Instead of smiling after taking a wicket, they were snarling. They were taking out something onto the somebody. If somebody taunted you on the field show it by scoring runs or taking wickets," Gavaskar said.

"Virat and some other youngsters were swearing at the opponents. That is like having a temperament of schoolkid cricket. They should not do that.

"When a Tendulkar, Dravid or a Laxman scored a century, they just raised the bat. By swearing or doing something like that brings down the focus," the former captain added.

Gavaskar, however, praised Kohli for the application he showed in his innings of 116 in India's first innings.

"What Virat has shown with his knock was that runs can be scored if you apply yourself. It shows he is a thinking cricketer. He will score lots of runs in future if he continues like that.

"His application was very good and took the attack to the Australians. That's important considering that temperament has been a let down among the batsmen and bowlers. He was calm and cool. I think he knew that he wants to make a case for his place in the Test team as a batsman," said Gavaskar.

"When Dhoni comes into the Test team, Saha cannot be selected as a wicket-keeper. Let's not jump the gun and it's too early to say that Saha can replace Dhoni as Test wicket-keeper. Dhoni has done a yoeman service to the country," he added.

Gavaskar also said that India still has the chance to save the Adelaide Test as the pitch was still assisting batsmen.

"There is a very good chance to save the Test. The Indian batsmen can take the lead from Virat and Saha and even Ishant who hung on for a while with Virat. Apply yourself and don't do anything silly.

"Nothing much is happening on the pitch except for odd balls climbing. I think they will get four-and-a-half or five sessions to bat on and if they bat sensibly they can save the Test," Gavaskar said.
