Hamilton: Previous engineer gave Bottas my secrets
Lewis Hamilton says Valtteri Bottas will have had access to many of his racing secrets in 2019, with a member of Hamilton's engineering team having switched sides in the Mercedes garage last season.
Hamilton's performance engineer Riccardo Musconi became Bottas' race engineer in 2019, helping the Finn win two of the opening four races of the campaign to appear a genuine title threat to his team-mate.
Bottas could not maintain form through the campaign as Hamilton eased to his sixth world title, however the switch behind the scenes did not have the bitterness that a similar situation between Lewis Hamilton and Nico Rosberg had done previously.
And Hamilton says that being aware of Musconi's presence on the other side of the garage merely gave him another challenge to overcome in 2019.
"He is a very talented engineer and naturally he wants to progress," Hamilton said. "No-one wants to stay in the same position and being lead engineer has got to be a great goal for an engineer.
