Mercedes' major F1 update package explained

The second Formula 1 test of 2019 has kicked off with Mercedes bringing a raft of new parts to its W10. With the help of images caught by Giorgio Piola in the Barcelona pitlane, Jake Boxall-Legge joins Ben Anderson to run through the changes in detail, from the nose and front wing, all the way through to changes made to the sidepods, floor and just ahead of the rear wing. They also explain why it would be too simplistic to assume these updates are a reaction to what the team saw last week in the first test, which means there could be more to come later in the season.
