"Unless a team wins overseas, they are not recognized as a force. I have always believed that winning in overseas conditions matters a lot. I am happy that we have done well at home. There is nothing wrong in using home advantage as every country does that", Gambhir told reporters at a promotional event here.
"But look at South Africa. They beat Australia in Australia and England in England. Actually, they are the No 1 side in the world," he said.
Gambhir, who has just started training after recovering from mild jaundice, said that "form is a state of mind" when asked about his century plus score in a first-class match versus Aussies and 60 plus score in a T20 game against Punjab.
"For me, form is always a state of mind. If you are confident and fearless and ready to express yourself, that's what matters the most."
"It's a good thing that India A team will be travelling to South Africa. This tour will give the players fair idea about what to expect when the senior team goes there. Normally, when we go to South Africa, we play a couple of practice matches and by the time we gauge the pace and bounce of the wicket, the Test series gets over. So it's a welcome move.
