The star all-rounder hasn't played any Test match since September 2018 to manage his work load and avoid injuries.
Gambhir reckoned that he was not a strong believer in the concept of injury management, saying that players have a limited shelf life as international players and they should not miss any chance to serve the nation.
"I'm a very strong believer in one thing, that if you're good, you should be playing all the three formats," Gambhir told Star Sports in his first interview since being appointed as head coach of the Indian team.
"I've never been a big believer that injury management, you get injured, you go get recovered -- as simple as it gets. Injuries are part of a sportsman's life. And if you're playing all the three formats, you get injured, you go back, get recovered, but you should be playing all the three formats," Gambhir, who starts his tenure with India's white-ball tour of Sri Lanka, later this month stated.
"When you're playing international cricket and you're good enough, you ask any of the top players, they want to play all the three formats. They don't want to stay and they don't want to be labelled as red ball bowler or white ball bowler.
"I am not a big believer in identifying people that we're going to keep him for Test matches or other formats. We're going to manage his injury and workload and stuff. Professional cricketers, you've got a very small span when you're playing for your country and you want to play as much as you can. And when you're in very good form, go ahead and play all the three formats," Gambhir added.
The comments from Gambhir have also provided a blueprint on Team India's selection going forward. A good run of form will make a player eligible for other formats as well, even if he has been tagged as a specialist of one format.
Recently, India legend Sunil Gavaskar also opined that Hardik Pandya should make himself available for selection in the Test format as well. "I'm hoping that, in these next two months, there will be some effort made to try and convince Hardik Pandya to come back to Test cricket," he said.
