Felipe Massa is feeling confident about returning to a circuit where he's won before, while Valtteri Bottas believes Williams need to improve their set-up in Barcelona.
Felipe Massa: "I have won in Barcelona before which is important as it means I can enjoy the race a little more. I know what it takes to win at the circuit so I can have a little confidence when driving there. Downforce is really important in Spain so we have to make sure the aerodynamic set-up is correct. We have been working on developing the car in this area. Barcelona is historically a place where teams bring upgrades, but as every team does this it's a case of whose upgrades make the most difference. I am really looking forward to racing again in Europe."
Valtteri Bottas: "As a team we are looking forward to Spain, once we are in Europe it's easier to bring upgrades out over a race weekend. The time gap between China and Spain has been really important as we have had time to improve the car, although how much we have moved forward is hard to say until we drive it. We haven't driven in Spain with the current car, which is unusual as in previous years we completed a lot of laps in testing, so we all know the layout well, but will need to work on the set-up."
