Christian Horner says the uncertainty over Esteban Ocon's Formula One future would be solved if Mercedes boss Toto Wolff was willing to invest in his junior talent.
Ocon's options for 2019 appear to be slimming, with the Frenchman likely to replaced at Force India by Lance Stroll -- son of the team's new owner Lawrence. On Friday, Toto Wolff accused Mercedes' rivals of "hidden agendas" and "lies" over Ocon's situation, as several teams have turned down the opportunity to sign the French driver due to his links to Mercedes.
