Ferrari driver Felipe Massa is shocked as to why he was penalised during the Spanish Grand Prix.

The Brazilian was forced to take an unscheduled tour through the pitlane on the 28th lap for ignoring yellow flags. The penalty meant that Massa slumped to 15th place and is still unsure of the reasons for his punishment.

"Honestly, I don't think I did anything wrong and I believe it is better to look into the detail of what happened, because I was in the middle of a group of cars and I definitely did not try to overtake anyone," said the Brazilian.

"It's a real shame, because up until then, the race was going well for me and a place in the top 10 was comfortably within my reach. I was in the group with the Red Bulls and the McLarens and I could match their pace."

Pastor Maldonado went on to win the race.
