Fernando Alonso mocked Lewis Hamilton over the Brit's stance on data sharing which he expressed earlier in the week.
In a UBS Q&A session which was broadcasted on Facebook, Hamilton said that he considers the practice of divulging data to a team mate as 'unfair', as it opens up a driver's secrets about braking points or racing lines, with the ability for the man on the other side of the garage to improve performance.
While Hamilton insisted that his remarks were not intended for new team mate Vatteri Bottas, he did admit he had inquired to his team on the matter.
At yesterday's McLaren launch, Alonso, who partnered with Hamilton at McLaren in2007, took a clear dig at his former team mate.
"He said many times that he was learning from the data," Alonso said.
"Mercedes are one of those teams that are using more of the data between the engineers to help the drivers, so he said something that was a little bit strange.
"If he was watching more data from Rosberg last year, maybe he would have won the championship!"
