Russell "not worried" about WIlliams' pace

George Russell has insisted he is "not worried" about his new team, Williams' rather slow pace - ahead of his 2019 move.

Last month, it was announced that Russell would be making the 2019 switch to Williams; joining on a multi-year contract.

Russell is currently at the top of the Formula Two standings and with his move to Williams, it is set to be a 'role-reversal' for the youngster - who may find himself right at the bottom of the grid for next season.

But Russell has insisted that he is "not worried".

"Formula 1 changes so fast," the 20-year-old told Finnish broadcaster C More. "Last year Williams was fifth in the Constructors' World Championship and two years before that they were third.

Williams are yet to name Russell's partner for next season; Esteban Ocon looks unlikely to move there, despite the talks. Robert Kubica, Esteban Gutierrez and current driver Sergey Sirotkin are also in the frame.

Asked for his preference, Russell replied: "I would be happy with anyone but it would be good if they are a really good driver to measure myself again. It's then important to build a good relationship with my team-mate so that we can push the team forwards."
