When it came to picking through the times of rivals Ferrari and Mercedes, Horner said: “Very difficult to say. I mean Ferrari look like they’re quick, Mercedes’ form [is] difficult to read at the moment. Are they holding something back? We’ll see this time next week; I think all will become clear.”
With Perez finishing Red Bull’s programme in Bahrain, Horner was particularly pleased with the feedback that the Mexican driver had offered on the performance of the RB19.
