Reacting to Team India head coach Gautam Gambhir's reaction to Ricky Ponting's remark on Virat Kohli's form, ex-Australia captain Michael Clarke said there are no friends on the field. "Off the field, fine...but on the field, you're playing for your country. You're not playing in the same IPL team," he added. Gambhir had said Ponting should think about Australian cricket.
