Kimi Raikkonen says he is satisfied to have completed his programme for the day despite a 'demanding' pair of free practice sessions hampered by niggling issues.

The Finn, making his much publicised return to the Scuderia for the 2014 season, maintained a relatively low profile in both sessions as he focused on acquiring mileage and evaluating Pirelli compounds.

Ending the two practice sessions with the seventh fastest time having accumulated 51 laps in total, Raikkonen was pleased with his day's work despite losing time in the morning.

"That was a pretty demanding day, because although we managed to complete our programme, it wasn't trouble-free. In the first session we lost a bit of time, but that didn't prevent us acquiring enough data to evaluate the overall handling of the car and the Pirelli compounds.

"This evening there will be a lot of work to do, especially to understand what didn't work and to try and improve for qualifying and the race."
