Brazil GP, Sao Paulo - Sunday, 1800 BST
Ferrari's Michael Schumacher outpaced Formula One championship rival Fernando Alonso in the second practice session for Sunday's Brazilian Grand Prix.
Schumacher has won seven races already this season
Schumacher was sixth fastest in a time of one minute 13.713 seconds with Alonso back in 10th, 0.107 secs behind.
Williams test driver Alexander Wurz set the day's fastest time of 1:12.547.
In the day's first session, Alonso did not set a timed lap while Schumacher and Ferrari team-mate Felipe Massa stayed off the track altogether.
Alonso requires a point to clinch back-to-back world titles, with Schumacher needing to win the race and then hope the 25-year-old Spaniard finishes outside the points if he is to clinch an eighth crown.
Wurz finished ahead of Briton Anthony Davidson in a Honda and German Sebastian Vettel in a BMW Sauber.
We need to fight for pole position and try on Sunday to fight for the podium
Jarno Trulli was quickest overall of the main drivers as he set a time of 1:13.483 in his Toyota around the circuit, with Jenson Button two thousandths of a second down for Honda.
Behind Michael Schumacher came brother Ralf, Super Aguri tester Franck Montagny, Kimi Raikkonen in his McLaren and then Alonso.
After sitting out the first session, Schumacher finally emerged 20 minutes into the second session, setting the fastest time at that point with his first timed lap.
The following lap he slid off onto the grass at Pinheirinho, and then the lap after he dipped under 74 seconds for the first time before returning to the pits.
He eventually went quicker later on as the session drew to a close while Alonso played it safe with just one lap.
The 25-year-old Spaniard, in fact, intends to pursue a cautious policy all weekend.
Our aim is clearly to try and win the constructors' championship and that
will require a one-two finish
"Everything should be normal, we try to do a normal race but the main objective at the end of the race is to be in the points and not win," said Alonso.
"We need to finish the race, that is for sure, and we need to avoid any risk, but at the same time I think we need to prepare for the race with an absolutely normal approach.
"We need to fight for pole position and try on Sunday to fight for the podium.
"And if with 10 laps, or 20 laps, to go and you are in a comfortable position then for sure you can drop your pace a little bit."
Schumacher said: "On the technical front, first impressions are good. The car and the Bridgestones seem to be working well.
"The situation seems pretty close, and from our side we are happy with the work we did.
"Our aim is clearly to try and win the constructors' championship and that
will require a one-two finish."
