June 19 (Reuters) - Red Bull boss Christian Horner recognised after Sunday's landmark Canadian Grand Prix that his runaway Formula One leaders could win every race this season. "On this venue yes, the gap is shorter... it's inevitable that they are closing, we'd be surprised if that wouldn't be the case," said Horner. If there is an Achilles' Heel in Red Bull's dominance, it is the current dependence on Verstappen for the top step of the podium. Should Verstappen suffer a setback, mechanical or otherwise, the chances of the second Red Bull coming through for the win are looking a lot less certain and rivals are sensing opportunities. Verstappen's last race retirement was in Australia in April 2022 and the last time he was beaten by someone not in a Red Bull was last November, when Mercedes's George Russell won in Brazil.
