Day 4 made for a wet track in Barcelona, but it was only artificial. However, there was nothing artificial about Ferrari’s pace as they once again went round fastest. Raikkonen was eight tenths of a second quicker than Max Verstappen, who’s Red Bull team have been looking stronger as they week has progressed. It was a disappointing day for Mercedes, as only Valtteri Bottas made it out onto track as a technical problem with the car meant that Hamilton couldn’t drive. It was an even worse day for Williams, who didn’t have a car after yesterday’s accident, poor Lance Stroll.
