Carlos Sainz may have signed Wednesday the fastest time of the tests, but the Spaniard is "very careful" because he expects more Ferrari and Red Bull.
The McLaren driver clocked a time of 1: 17.14 Wednesday morning, beating his nearest rival – Sergio Perez – by seven tenths.
It was the second day in a row that McLaren finished first overall, but Sainz downplayed the pace of the team.
"There is still a lot to improve," he said.
"What matters in these seven or eight hour days is that every time I'm on the track, by car, I think things have progressed.
"The balance of the car has improved over the past few days, allowing us to extract a little more, which means the team is working well.
"We understand and correct the underlying equilibrium problems little by little, but we still have a long season and great areas of improvement in which we have to continue to work.
"We are still not where we want to be. This is definitely the right answer. And we must continue to work hard.
He could have been ahead of everyone on Wednesday …

"So, I am very careful and calm."
