Alonso concerned about track conditions

Following overnight resurfacing of the hairpin, track officials have continued work on parts of the circuit in the hours before the start of the race.

F1 race director Charlie Whiting took a tour of the circuit two hours before the start, and workers have been seen applying chemicals to the track at Turn 1 - where the resurfaced asphalt has been breaking up as well.

With track temperatures rising dramatically, Alonso said it could get as bad as needing to bring the safety car out just to finish the race if the tyre marbles and track breaking-up continued to deteriorate.

"I think it is not an easy problem because the race can be much worse than qualifying, and if it is much worse it will be impossible to run," he said.

"There were some corners that were very, very on the limit and you needed to put two wheels on the grass to avoid touching the marbles. So I think the race can be even a safety car situation if we cannot run any more."

Felipe Massa echoed the chorus of drivers predicting trouble in the race if overnight work has not sorted out the situation.

"If it is a strange race, if the asphalt stays like it was in qualifying, then it will definitely be a crazy race. It is much worse than normal as the marbles are coming on the line and off the line even more."

But Massa played down any talk of a possible drivers' boycott in the event of the track condition getting worse.

When asked for his feelings on when a strange situation because a dangerous situation, he said: "Forget that. It doesn't exist. It is a dangerous situation but it is not dangerous to risk our life. It is just low grip on the corner (hairpin). And it is a very slow corner."
