Mercedes boss Toto Wolff hopes Valtteri Bottas' future will be resolved by the Asian leg of the 2017 Formula One season in mid-September.
Bottas signed a last-minute one-year deal with Mercedes to replace Nico Rosberg, following the reigning world champion's shock retirement in December. The Finn has made an impressive start at the German manufacturer, scoring two wins to sit third in the championship and just 33 points behind championship leader Sebastian Vettel at the half-way stage of the campaign.
Despite Bottas' strong start, Mercedes has previously been non-committal about whether he will remain as Lewis Hamilton's teammate in 2018.
