Liuzzi downbeat after difficult day

The Italian ended up 20h overall and was far from happy after suffering an imbalance problem and electrical issues.

"Overall this was a very difficult day," he said. "Since the morning session we had a problem with the car reacting strangely in the corners, with a bit of an imbalance between right and left turns.

"We never found the right set-up despite changing several things on the car. I continued to struggle in the afternoon, when I also had an electrical problem which meant I had to stop before the end and before doing a run on new tyres, so we are lacking a bit of data."

Teammate Sebastian Vettel was little happier with his car, after ending up 18th in the second session.

"We were quite happy with the early runs this morning, but after that the day seemed to get more difficult," he said. "Of course the track conditions are very different to last week when we had quite a good test session here.

"That was actually my first test session in this car and certainly, every lap helps. But now we have to concentrate on this weekend and hopefully we will be able to work out what to do to get more pace out of the car."
