Robertson surely knows a thing or two about Australian cricket despite getting little time to follow the game due to his hectic professional schedule and always loves to watch an India-Australia contest.
"It's sad day for Indian cricket that Tendulkar is retiring from the game. He is an exceptional player. Everyone knows about the great rivalry between the two finest cricketers -- Shane Warne and Tendulkar. It was a treat to watch both of them contest," said Robertson.
The 31-year-old felt that there were no more rivalries on display in cricket due to the advent of T20 format.
"Earlier, there used to be a fierce rivalry between the two sides but nowadays, you hardly see any rivalry. The two sides don't compete that fiercely but that's how it has become. Everyone is playing the T20 game; everyone is going the T20 way. For me, Test cricket is always important."
