Stand-in captain Gautam Gambhir was all praise for the youngsters' fine show in the just-concluded series against the West Indies but warned that a tougher test lies ahead for them during the upcoming tour of Australia.

"It always helps to get runs under your belt but in Australia those are different conditions. We all know this is not what we're going to get in Australia. Australians are tough nuts to crack and will come hard at us," Gambhir told the mediapersons after completing a 4-1 ODI series triumph over the West Indies here last night.
