Jarno Trulli put every bit of his twelve years' Formula 1 experience to good use to snatch an unexpected seventh spot on the starting grid for this weekend's European Grand Prix in Valencia, as team-mate Timo Glock confessed to being baffled at his sudden loss of form.

Doubtless boosted by his Hungaroring podium finish of three weeks ago, the young German has generally held the upper hand over his Italian team-mate during the course of the weekend - the sport's first around the all-new, harbour-side Juan Carlos I Marina circuit in the Spanish city - with the latter suffering from myriad problems on his Toyota from the onset of practice.

It was Trulli, however, who pulled it out of the bag when it mattered most, overcoming a complete lack of running in the final free practice session on Saturday morning to sensationally top the times with a late effort in Q1, place fourth-quickest in Q2 and ultimately wind up on the fourth row of the grid.

"After our difficult practice yesterday, we completely changed my set-up for today," the 34-year-old explained. "Then we had a gearbox oil pump problem this morning that meant I could not try it out.

"In a way that meant I was driving blind this afternoon, but I used my experience, I concentrated very hard and I made it through into Q3. I made a mistake on my last run, but I am still very happy with what we achieved today.

"I'm also delighted with the way the car is developing, and the fact that we can always fight for the top ten and score points. That is again our target tomorrow. It's important and realistic and it will be an interesting race. Here, more than anywhere, anything can happen and it should be a great event."

"I don't know what went wrong," confessed Glock, who will begin the race from 13th place after failing to make it beyond Q2 and antagonising a number of other drivers en route by getting in their way. "I just didn't get the lap together in the second session and that was that. We definitely had the chance to be higher, in the top ten, but it was a difficult qualifying in the end.

"For me the prime tyres seemed to work better, but I struggled to get temperature into the tyres in the first sector of my last lap in Q2. It was just not my day today. I had a heavy cold overnight and didn't feel particularly well, but no excuses.

"I think the car was good enough, but it just didn't work out. Of course we will do our best to make up positions tomorrow. There could be safety car periods, so we will aim to make the most of our freedom with the strategy."

Toyota is currently four points clear of Renault in the hotly-disputed scrap over fourth place in the end-of-season constructors' rankings, but of the four teams chasing the spot - Red Bull Racing and arguably Williams are also in the mix - Trulli has put the Cologne-based concern in pole position to extend that advantage on race day in Valencia, even if the work does not end there.

"Altogether it has been a very difficult day and a disappointing qualifying result," summed up the big-budget Japanese manufacturer's senior general chassis manager Pascal Vasselon. "Yesterday we had a very competitive Friday, especially with Timo, and now things have turned around.

"Jarno did a fantastic job because he could not run in P3 this morning due to a gearbox oil pump problem, but that did not stop him and all his laps apart from his last lap in Q3 were very good.

"For Timo, today was not as successful as yesterday. He was on the pace in Q1, but Q2 did not go as expected so we will have to investigate what happened. After the overnight rain the track was green again today, but the tyre situation is clear.

"The positive thing for us is that we are in good position to defend against safety cars tomorrow, and make sure that both cars are not caught out by the same safety car period."
