Nico Rosberg has said a lack of confidence can lead to Lewis Hamilton making “mistakes” as he goes through a familiar phase.

Hamilton and Mercedes are winless in three races so far this season, the first time this has happened since 2014, and the Brit was never in contention for both qualifying and the race itself in China.

Hamilton going off the pace is nothing new to his former team-mate, who cannot wait to find out if he can get somewhere near his best again in Baku.

“Lewis is not in form but he’s always had such phases,” Rosberg told RTL television.
