Tonio Liuzzi reckons his penalty for impeding Nico Hulkenberg in Silverstone qualifying was unjustified, as others have got away with blocking him earlier this season.
The Italian regularly complained of traffic spoiling his qualifying laps in the early rounds, but he was the one accused of blocking yesterday, after an incident with Williams driver Hulkenberg.
The stewards opted to give Liuzzi a five-place grid penalty, dropping him from 15th to 20th.
"It was at the end of Q2. I thought that he was coming out of the pits as I got a message from the team to stay in front because they thought that he was on an out-lap so I wanted to stay ahead," Liuzzi explained.
"I don't think that I should have been penalised because I lost three races in qualifying because of Williams in the middle of the track this season. But we have to take it."
He is not optimistic about his race chances starting from so far back.
"It's not a circuit where you can easily overtake so points are going to be a big challenge, but we'll try hard," Liuzzi said. "There were some predictions for rain at the beginning of the weekend, which would maybe help, but we have to take it as it is."
