Lewis Hamilton's former rival Nico Rosberg believes Valtteri Bottas has gotten under the reigning champion's skin at the start of the 2019 campaign. Bottas beat Hamilton comfortably in the season-opening Australian Grand Prix and has shown impressive form in Bahrain so far this week.
Hamilton failed to win from pole in Australia for the fourth year in a row two weeks' ago, a run started by Rosberg's 2016 triumph, which preceded the German's title win that year.
Bottas needs a big year after failing to win a race in 2018 and got off to the perfect start.
And Rosberg, who knows better than most about getting the better of Hamilton, believes Bottas is on the right track to do similar in 2019.
