"We haven't solved the issues yet, but we had similar issues last year at some point of the season. We were pretty okay at the beginning of this season, and then it seems to have turned a bit worse. Hopefully, we will get back to where we were earlier on, but we will see now if we have made improvements or not, then we will go from there

"We tried many things [at Monza] and were pretty happy with the car, but you never know from a test. It can be a good test and then you come to the next place and it is a different circuit with different conditions. It can get back to where it was. Hopefully, we found something and can be stronger, but it is too early to say. We had a good feeling from the test but we will see now."

Raikkonen appeared more confident that there would be no repeat of the engine failure that sidelined him in Valencia - and Massa in Hungary - after Ferrari traced the most likely cause. The team has admitted that it knew Raikkonen went to the grid in Spain with the potential for a failure as his engine was unchanged from Hungary and approaching a similar stage in its 'life' to the one that let Massa down within sight of the chequered flag in Budapest.

"I think we know what the problem was, and it was more or less the same issue with Felipe's engine the race before," he confirmed, "Hopefully, we've fixed it - so far in testing and on the bench, we have been okay. It can happen again, but we are pretty sure that we have fixed the problem and it should be fine."
