Team-mate Sutil meanwhile said he was confident of turning his fortunes around, with the current Force India
machine being the 'best car he has driven' in his F1 career to date.
“Wherever we have gone so far the car has looked competitive – and that includes some very different tracks,” he said. “It's a good sign for the rest of the season. Of course, Monaco will be the first real street circuit, but I think we will be quick there. The car is very strong in the front with a very neutral balance so it's very driveable.
“Despite everything that has happened during the last four races, I remain positive. Most of the things that happened were out of my control, but still I believe we can improve certain things to avoid mistakes in the future. We as a team have to stay confident and work on solving these small problems. The car is fast and if we have a perfect weekend, which is our aim all the time, I'm sure the podium will come soon.”
