Christian Horner is expecting Mercedes to be "quick" at the French Grand Prix, giving Red Bull a new but familiar rival this season.
Those two teams were the heavyweights last year, with Lewis Hamilton and Max Verstappen going toe-to-toe for the title. The Dutchman eventually wont hat duel, but Mercedes kept their grip on the constructors' championship.
This year the Silver Arrows have dropped away, with Ferrari taking their place as the team tasked with stopping Red Bull. Mercedes have been playing catch-up in terms of car performance, and it looks like their hard work might be starting to pay off.
